1996 Hong Kong film directed by Peter Chan

As adults, best friends Julien and Sophie continue the odd game they started as children -- a fearless competition to outdo one another with daring and outrageous stunts. While they often act out to relieve one another's pain, their game might be a way to avoid the fact that they are truly meant for one another.

Nine years after Jesse and Celine first met, they encounter each other again on the French leg of Jesse's book tour.

A young man and woman meet on a train in Europe, and wind up spending one evening together in Vienna. Unfortunately, both know that this will probably be their only night together.
