I saw a movie a few years ago where *spoilers* a man was viewing his life in reverse. The audience (and I think the man) doesn’t know this until the end, though. We finally realize that he is dead and the whole movie is his life flashing before his eyes. I think he may have been killed in a car accident and he may or may not have been drunk and killed someone else as well.
The movie was in color and in english. The main character was a man (not really old but not really young) and I remember him having red curly hair but that could be the complete opposite of the truth. I have no idea.
Just a guess – “The Death and Life of Otto Bloom”?

Shuffle (2011)

I think it’s Memento (2000). He is remembering everything backwards and writes notes on himself.
