I just got a request from a friend of mine who is looking for a certain movie, but alas I couldn't help her... maybe you can.
She describes the movie as follows :
It's a french movie about a man who is living at a highway gas station. He cannot leave the gas station due to some psychological trauma ... but he wants to leave because of his girlfriend. According to my friend there is also some singing like in Bollywood movies.
She saw the movie on german television approximately two years ago on german/french channel ARTE.
I'm sorry I don't know anything else, though I think the "man living at gas station" could be pretty obvious for anybody who has seen the movie ...
Thanks in advance.
