Only problem with this is that the friends can't get in to see it, then...seeing as they don't have their tickets.
That's stupid, though. I don't go to theatres very often, but I hate people who go there to chat it up. FUCK YOU! I paid to see and hear a goddamn movie, and I get to see a movie and hear a different soundtrack? Fuck that! They should have "anti-noise police" in theatres to keep people fucking quiet!
