Revealing mistake: When the boy accidentally hits the old man with the ball, he falls over. Note that you can see the stuntman's full head of hair as he hits the ground. When you return to the close-ups of the old man as he gets up, that extra hair is gone.
Trivia: In the country where the film was made, extras are not hired. The people in the background are just normal people. Watch the background during the scene where the young couple is talking in front of a subway staircase and you will see a boy flipping off the camera.
Londet: Great boobs.
Daniel Michon: All this... and you look at that?
Londet: You look at what you like. I'll look at what I like.
Daniel Michon: ...that legend is just another one of your damn lies.
Julius: You could make it true. What are legends anyway but stories about ordinary people doing extraordinary things? Of course, it takes courage and imagination... not everybody has that. I may be an old fraud Daniel, but I do know this: something that two people who are in love create together against impossible odds, can hold them together... forever.
