Thing is, with that movie, reversing the order of the scenes doesn’t put things in their place, it actually makes things far more confusing. It’s a common belief that Memento is “in reverse” or “shown backwards” but that isn’t really the case. It’s actually shown forwards and backwards at the same time, ending up in the middle.
It can get a bit confusing but I’ll try to explain. I know you said it had been explained to you, but maybe I can improve on that.
There is only one timeline:
(Start of the film) “A” ------ Middle ------ “B” (End of the film)
- Segment “A”, presented in black and white, covers the part of the story from the start to the middle. This segment is presented to us in chronological order.
- A single scene at “middle” that starts in black and white and ends in color.
- Segment “B”, presented in color, covers the part of the story from the middle to the end. This segment is presented to us in reverse chronological order.
The genius is in the editing. The scenes are shown to us in such a way as to force the memory disorders of the protagonist on to the viewer.
Let’s just say each segment has five parts, so then the theatrically presented order is something like:
A1, B5, A2, B4, A3, B3, A4, B2, A5, B1, Middle.
But to view in chronological order, you need to re-edit them to:
A1, A2, A3, A4, A5, Middle, B1, B2, B3, B4, B5.
That’s actually way over simplified.
The following forum post explains the convoluted way you would need to watch the film in order to see it completely chronologically, which does defeat the filmmakers’ intent, but is cool to check out at least once:

It goes a bit like this:
Chapter 1
Chapter 2
Chapter 3
10:12
Chapter 5
Chapter 6
26:43
31:41
Chapter 8
45:00
…and so on.
You’ll find that by viewing the film like this, the first half is entirely black and white, while the second half is in color, the two being linked by the “middle” color transition scene. In actual chronological order, the narrative is very straight-forward and easy to understand.
A-freakin’-mazing, IMO
Some of the DVD / Blu-Ray releases of this movie have easter eggs that allow you to view the scenes chronologically. Alternately, if you Google for the chronological version, it is available for viewing.
<-- Huge Christopher / Jonathan Nolan fan here. If you end up figuring out Memento and are interested in more, check out Christopher’s first movie, Following. It’s also presented in a strange chronological order, gritty black and white … an excellent film.
P.S. Yeah it took me like six edits to get this thing right LOL.
