I saw A Very Long Engagement last night, and if you go see it, I have a recommendation:

Just before it starts, stand up and tell your fellow audience members, "Jodie Foster is in this movie!! Yes, that's her! That is Jodie Foster! Speaking French! So now you don't have to keep asking the person next to you if that's Jodie Foster, because it is!!"

Trust me, it'll save you a lot of heartache about an hour in.
