SLAP HIM IN THE HEAD!
Sick my wife on him. She lives for this and has no fear. I would overreact and end up being kicked out or worse. She would socially embarrass the culprit and have the whole theatre against him in seconds. It's happened. It's not pretty.
Ask him nicely to please not talk during the movie or get up and change seats.You could get the manager too.
Probably way to patient ..how have you been by the way?Great question too.
Tap them and ask them to quiet down and if they won't call an usher? I don't have time to get into an argument I wanna see the movieee.
I haven't been to the cinema in ages - too many kids fooling around spoiling the movie. I'd sooner wait until the DVD comes out and watch the movie at home instead.
