Joseph Kahn Detention 2011

I didn’t love DETENTION the first time I saw it.

I probably got a little too excited when I heard it was going to be a John Hughes style high school comedy married to Joseph Kahn’s hyperactive directorial style, slasher movie tropes, and time travel craziness. I was a big fan of the over the top zaniness of  Kahn’s  feature film debut TORQUE, and when I read him describe the stunts in TORQUE in relation to Michelle Yeoh’s bike train jump in Jackie Chan’s POLICE STORY 3: SUPERCOP, I realized he was a man after my own heart. Kahn funded DETENTION out of his own pocket and it was guaranteed to be an uncut artistic mind blower.

And then I watched it. And it didn’t instantly click with me.

I wasn’t sure why.

“Oh man! Did you see the DENTION trailer!!!???” friends kept messaging me “It looks like something you would make!”

At first, I shrugged off those assertions with a quiet whisper of “It’s not like me! I’m a pure original!”,  but it didn’t take me long to realize everyone was right. DETENTION was the same mixture of  anything goes splatter comedy, camera gymnastics, and exposed beating heart that I have been writing and shooting in some no-budget forum since the day I picked up a camera – except in DETENTION it was done right. The film mirrored my obsession’s so closely,  I had been unconsciously over critical of it: Some of the acting was a little wonky, a few jokes landed flat, the use of digital blood was a little distracting , and my biggest problem of all…

Look, I’m not Neil deGrasse Tyson. I don’t want to suck the fun out of everything. I understand that time travel doesn’t have to be logical as long as it makes emotional sense. DOCTOR WHO does it all the time. THE TERMINATOR doesn’t care. LOOPER. Well, don’t get me started on LOOPER.

I love time travel. It’s one of my favorite sub-genres for the simple reason that it offers infinite possibilities, but also carries a series of checks and balances. The best stories are the ones that that have fun with the storytelling mechanisms the concept offers, but then reveals the consequences of that fun – you don’t realize you’ve been experiencing a puzzle until every piece locks into place

DETENTION doesn’t care about the logic of its time travel because it’s all in the service of the jokes. I get that, but man, it still bugged me. The rest of the film was so dense, so layered, and so well thought out, that it felt like I was missing something. I knew that I wasn’t, yet I couldn’t shake that feeling.

I watched DETENTION again. And again. And again. Obviously, I fell head over heels with it. How could I not?

In anticipation of BODIED having its premiere (programmed by my pal Peter Kuplowsky at Midnight Madness!), I decided to give DETENTION another watch.

For some reason, this time everything clicked. My mind went into overdrive. It all became clear to me.

And this happened:

This will make zero sense if you aren’t obsessively familiar with DETENTION. Go watch it now. Come back.

I don’t believe Joseph Kahn or co-writer Mark Palermo thought of any of this nonsense. They had bigger concerns like pacing, comedy, drama and making a damn movie. This ‘article’ is the work of someone who had zero involvement with the complexities of bringing DETENTION to life.

I am not adept at mathematics or science in the slightest. If you find a fatal flaw in my logic, you’re probably right. Your No-Prize is in the mail!

These rules apply only DETENTION. Other films may have a completely different set of rules.

Now, lets get started.


Joseph Kahn Detention 2011

If Riley and Clapton go back and change their past, how can they build a time machine to go back to change their past?

Or the more classic flavor: If you go back in time and kill your grandfather, how can you be born to travel back in time to kill your grandfather?

Well, there’s a real easy solution: The act of travelling backwards in time creates an entirely separate time stream.

If you go back to the past and kill your grandfather, from the point of your arrival, you are creating a new time stream.  If you kill your grandad (poor guy) then switch your time travel machine to jump FORWARD in time, you will find yourself not where you came from, but from the future you have created by your senseless murder (unless he was a bad dude)

No more paradoxes!

Here’s an illustration I made in  PAINT (rip) to illustrate this point:

Every time you travel back in time, you create a new timeline. The colors denote the changes in the new time line from the point of the traveler’s arrival. SECOND LINE: If you go back ten minutes, everything will be different from the point you arrive onward because you’re in a new timeline. THIRD LINE: If you then go back eight minutes, you will arrive in a timeline where two minutes previous you traveled back and changed stuff. FOURTH LINE: If you go back twelve minutes, you will never experience a present a past you traveled to. FIFTH LINE: If you go forward, you will be in the same thread you have created. Yes, it’s complicated.

In the universe of DETENTION: There can only ever be one of you. If you travel back to yesterday to meet yourself, it won’t work, because your future presence will erase yesterday’s version of yourself.  This works the same for travelling to the future. If you travel from your present to the future, your future self will disappear when you arrive. The time traveler always take precedent.

This explains how Riley and Clapton can go back in time to 1992, witness the apocalypse, and then jump back six minutes in the past before the apocalypse and not run into each other. It also explains how they can go to the future and not have to deal with alternate universe doppelgangers.

This rule (like all these rules!) is never discussed in the film (because I made it up), but nobody ever meets themselves, so there’s no conflict.

Phew! Well, we solved those logic problems, right?


Aw crap.

The shoe in the glass cabinet. The photo of the girl giving a blowjob to a bear. The photo of Verge and Sloan from 1992.

You see them at the start of DETENTION and at the end they are all revealed be the result of Riley and Clapton travelling back in time.

This could easily be hand waved away by applying the multiple timelines theory, right?


Joseph Kahn Detention 2011

In the film, all of these things (blowjob, photo and boot) happen in the past of a timeline where young Verge (Dane Cook) doesn’t set off his bomb, which means he doesn’t get a scar on his face. Riley and Clapton jump to the future and find Verge and Ione have been together since high school, which means the timeline which is the one we’ve been watching since the start, with Dane Cook as an angry principal with the photos and shoe, is impossible.

Now, I will tie myself in knots trying to justify on this could work.

Lets talk about the quantum mechanics many-world interpretation.

For every choice you make, there’s a different universe where you make every single other possible choice. Did you just take a sip of water? There’s a universe where you didn’t. That pencil on your desk? There’s universe where you just stabbed yourself in the eye with it.

Not only is anything possible, but it has happened, somewhere.

Got it? Good.

Time travel works in many different ways, you can have the multiple time streams theory like I presented a few paragraphs back, but you can also have the idea that time can be locked and the present will reflect the changes that will happen from someone travelling back from the future and changing the past. This is a locked loop, but that means what happens in the present is a paradox, because there MUST BE a ZERO POINT TIME STREAM to begin the act of time travel –  a time stream where someone travels back to the past for the FIRST TIME. The ZERO POINT TIME STREAM is the first time someone travels back and everything beyond their arrival from that point on now a LOCKED LOOP, which still works with the the multiple time stream theory, because time streams never stop existing, they are merely left behind when another one is created.


The version presented in the film DETENTION  is not the ZERO POINT TIME STREAM.

We could be watching time stream 2 or even 9 in DETENTION. What that means, is that the Riley we see in the film comes after a Different Future Riley travels back in time to 1992. Why? It doesn’t matter. She went back, did some stuff VERY similar to what we see in the film version of DETENTION (many worlds!), which includes the blow-job bear photo and kicking her shoe in the glass case, but the bomb did go off in science class and scar Verge. In 1992, The Future Time Travelling Riley we never see (who may or may not have been with Clapton, it doesn’t really matter)  then traveled to the future of the ZERO POINT TEAM STREAM, went into hiding or died. After all that, time goes on, her parents conceived and gave birth to Riley, that Riley grows up, and we catch up with her in the second scene of DETENTION.

I’ve essentially created an entire prequel to DETENTION  to explain some jokes.


Joseph Kahn Detention 2011

“The irony of Sloan’s story, if you pay attention to it, is that it doesn’t make sense.” – Co-Writer Mark Palermo on the Commentary Track 

This is going to be like trying to explain the plot of John Woo’s FACE OFF “See, Nic Cage is John Travolta whose pretending to be Nic Cage and…Urghhhhh”

Please get out some graph paper.

In the film, the character of Ione switches minds with her mother Sloan. Ione’s 2011 Brain jumps to her mother Sloan’s 1992 body (played by the same actress as Ioene 2011), Ione’s mother (Sloan) 2011 brain jumps in the brain of Ione’s 2011 body to win a dance contest, and Sloan’s 2011 body is abducted by aliens (so she isn’t comatose due to being brainless in 2011) Now, this creates problems only because of how the film plays out at the end.

Ione 2011’s brain is is in Sloan’s Body 92, and she is pregnant with Ione’s 2011 brain and body. At the end of the movie it’s shown that Sloan’s 2011 body has the brain of the time travelling Ione from 2011 and the Ione’s 2011 Body has the brain of her Sloan from who knows where…Uh…What…Did the brains get switched back?

Here’s how I shakily justified it to myself- Sloan’s 1992 brain doesn’t exist anymore in 92. Her daughter’s brain jumped into hers and she was erased. Ione’s 2011 brain in Sloan’s 92 body gave birth to Ione’s Brain and Body 2011, and this version of Ione 2011 had to deal with an adult that was trapped in constant teenagerhood (let me have this) and she had to become the adult in the relationship. There is no way in hell this is what the Kahn and Palermo intended.

Boom! Problem solved. Make sense? No. Okay. Well, it makes sense to me!

That’s okay. None of this really matters.

It’s simply the rambling of a fan that enjoys a film so much he makes up ways too find new layers to discuss it.

Hopefully, you watched DETENTION in an attempt to puzzle all of this out OR to prove me wrong. Either way, it means you watched DETENTION. You win.

You have a conflicting theory? Let us know in the comments!


I originally got thrown off by the reveal that the killer got his face burned in the past, but that doesn’t matter. He is a killer in every timeline we see in the film and its unrelated to the time travelling (as far as we know)

There’s a lot of WAIT, BUT WHAT IF…in these rules: Like what if a time traveler goes to past, and hangs around, and then their born…does that mean they will baby disappear if the time traveler take precedent? Those type of paradoxes never happened in the film to my knowledge, so I didn’t worry about it.

The film states that all time streams run concurrently with each other (“the world will end in ten minutes in 1992 which will end time here”). I’m cool with that.

I wrote all of this to the strains of Hanson’s MmmBob.

No, I don’t understand the time travel in PRIMER.

You should watch TORQUE. That film is great.

And if you haven’t gotten you fill of insane fan theories based in zero reality, you should check out the great documentary ROOM 237.

“What about the kid who’s been in detention for 19 years and has never aged?” Come on, DETENTION has a teen with fly blood and a space bear. It’s just a movie!

Lets all dance the robot.
