I'm a big fan of Christopher Nolan, Quentin Tarantino and Clint Eastwood.

Since few of their movies have already posted here, I would like to post one of the different attempts taken by Christopher Nolan -
Memento (2000)

It was the first time that I really felt how can someone engage you with his idea and satisfy you by executing the same on the screen. The reverse storytelling concept was the best thing about the movie

The sujet (syuzhet), or the presentation of the film, is structured with two timelines: one in color and one in black-and-white. The color sequences are alternated with black-and-white sequences.
The color sequences include a brief overlap to help clue the audience into the fact that they are being presented in reverse order. The purpose of the fragmented reverse sequencing is to force the audience into a sympathetic experience of Leonard's defective ability to create new long-term memories, where prior events are not recalled, since the audience has yet to see them.

And about Christopher Nolan – He is the library for film industries of any countries.
