Need help with a foreign film

[Patton]

I saw a trailer a while back (seems like it was on a movie that also had a trailer for A Very Long Engagement) and it had a man and woman and they were friends when they were kids and they had a trinket of some sort that they passed back and forth and they would dare each other to do stuff and they had to do it.

Ringing any bells?

I know the movie, but can't remember the name right offhand. Give me a few minutes.

Okay... it's JEUX D'ENFANTS (LOVE ME IF YOU DARE)

That's it. Thanks very much.
