Movie date help?!?!?!?

ok so i'm going to a movie with my boyfriend tonight with 2 of my friends and one of the girl's crushes. i've been to movies with my boyfriend with just the two of us before, but never with a group. so what should i do? i mean is kissing during the movie too much? usually he has his arm around me and we're very close & cuddling, but is that too much pda for a group setting? input please :)
