Seen many years ago. B&W I think. I don't remember what language -- it may have been silent.
A man has the same routine every day -- wake up,shower, get dressed, eat the same breakfast, take the elevator down work, come home, take the elevator up…you get the idea.
One day he decides to try something -- on his way down in the elevator, he tries to see if he can undo his tie then re-tie it before reaching the ground floor. He does.
The next day he tries to do more, like undoing his tie and unbuttoning his shirt, then redoing all.
Every day he does more until he's actually preparing and eating breakfast on the way down.
And so on.
I think one morning a woman gets into the elevator with him and makes things more interesting.
Does this ring a bell?
