I like Tom Hanks. I have, ever since "Bosom Buddies" and, let's face it, "Bachelor Party", the movie that it's embarrassing to admit is really really funny. And of course he's a huge space exploration fan.
I'm almost positive I won't see "Angels and Demons", since I read The DaVinci Code and was pretty meh about it (and never saw that movie either). Still, here's Hanks on The Daily Show talking about the movie, which features antimatter; near the end he talks about CERN and the Large Hadron Collider with enthusiasm if not 100% pronunciational accuracy:

ObScience: the amount of antimatter created in a collider is extremely minute, enough so that it doesn't do any real damage when it smacks into things. We're talking billions of antiparticles, sure, but it takes billions of billions to make any significant bang.
