Can me and my friend be arrested for sneaking into a movie theater?

My friend and I went to go see a movie. We paid for it and saw it. After it was over, we snuck into another movie to watch it. We got kicked out and the manager said he is going to call the cops. Can we get arrested for it? Some other things that may factor into the decision are that the movie ticket only cost 7 dollars, we are both 18, but I live with my dad because Im still in highschool
