Can you think of any action-ish movies that aren't violent and are interesting to a general crowd?

I’m in charge of choosing the movie for a get-together with friends, tonight. Half guys, half girls. The guys have informed me that they only like action movies, and the girls tell me they don’t want to watch violent films that hinge on explosions.

I’m trying to think of something in-between.

They are international students, so they haven’t seen everything. Old stuff is okay. Any suggestions, please?

Also, what about Serenity? I haven’t seen it; does it fit the bill? I love Joss Whedon, so I thought, maybe…?
