Sorry this is off topic but I must give Josh his props.
Well Josh, despite all of the references below (and from my previous post) I have to agree with you.
Seriously, your are correct "Memento" is a linear film. I was wrong (as are all the people below) and you are correct. My hat's off to you, very good! (see last link)
I'm including these links to show how many people, including myself, have the mistaken belief that Memento is a non-linear movie (and there were many more).
Screenwriting Structure Part 4: Balance By The UnknownScreenwriter
Excert from above link:
If you recall when Pulp Fiction came out, quite a few movies attempted to re-bottle the non-linear formula and do what Quentin Tarantino did and most of them failed miserably. One that didn't however, was Memento.
Both screenplays tell their stories in a non-linear fashion but they're certainly not derivative. Lots of reviewers have compared Memento to Pulp Fiction because of its non-linear storytelling but Christopher Nolan didn't didn't rip PF off. Rather, he went down a similar road that Tarantino did i.e., both created their structure from what they'd seen done in novels and as he got further into the script, he realized that he wanted the audience to more or less share Lenny's point of view, so he tweaked his structure to reflect that by weaving in more voice-over as well as utilizing camera angles that enabled US to see things through Lenny's (the Protagonist) eyes.
Memento - Reviewed By: Professor Steve
"With its non-linear style and intricate plot, the movie only gets better and more understood after repeat viewing."
Memento - Rotten Tomatoes Summary
"Memento" mines this psychological terrain, using non-linear film narrative to mirror Leonard's own effort to interpret the random pieces of evidence he hoards.
Non-Linear Movies by Randy Hoyt
I do contract web development work for Blockbuster, the movie-rental company headquartered here in Dallas. I had a conversation about non-linear movies a few weeks ago with some of my colleagues there. Two of my ten favorite movies (Eternal Sunshine of the Spotless Mind and Memento) are undisputably non-linear movies, and two others (The Usual Suspects and Pan’s Labyrinth) make an extensive enough use of flashbacks or frame narratives to be classified as such by some. Let’s just say I like movies that are not in chronological order.

Harry's Movie Review from 'Ain't It Cool News'
[I]"What is MEMENTO? Well it is a non-linear tale about a handicapped avenging would-be detective seeking revenge for his ‘dead wife’. Looking for the J.G. that did it."[/i]
Memento: Movie Review By Joe Lozito
"The story doesn't rely on surprises endings or twists, in the vein of "The Sixth Sense" or "Fight Club". "Memento" has no trouble living up to scrutiny and, in fact, begs for repeat viewings by the nature of its non-linear structure."
Memento reviewed by George Perry of BBC Films
"The structure of Christopher Nolan's fascinatingly original second film is determinedly non-linear."
And finally, from the Director himself -
INTERVIEW: Mindgames; Christopher Nolan Remembers "Memento":
"This one was actually clearer because -- the AD was one of the first guys to point this out -- this is not a nonlinear film; this is an extremely linear film. You cannot move a scene. It was very tough in the editing to get it down to the right length because you could not lose a scene, otherwise you've lost your link between these things. It's very, very strongly linked scene-to-scene, much more so than a conventional movie."
Note: From these comments it appears that even Nolan considered it a non-linear film until the above was pointed out to him by the AD.
