I'm sure this has been asked a dozen times before, but like the title says; what acting qualities or skills do you look for when casting a film?
I did not work so much with theatre actors, but noticed that too. We made two films with an actor, who was in a local theatre group (not professional, just for fun). Both movies were parodies, therfore his overacting was not such a big problem. The first role was a drunk (later hung over) guy, so his acting based on personal experience"We look for actors who have done some live theatre work"
I am VERY hesitant to hire stage actors unless they have significant film experience as well. The two are so completely different.
This is the biggie right here. If they can't pass this test, they'll f up your production. Imagine if you have 3 or 4 of these kind of people in your cast.
