I am shooting a suspense thriller short film and there is a psycho femme fatale character. Now in most movies them female villain who uses sex as a weapon is a good looking, thin to average sized woman. I don't have a lot of actresses to pick from and don't wanna hire on beauty or body size mainly, because that would be kinda shallow really. I wanna hire based on acting skill. So does it matter if the femme fatale is not good looking, or is over weight to most mature audiences? I want to send this into film festivals to get my foot in the door as a newcomer director. Therefore, I want to make the right casting call that most critics will get the right tone from, and not feel that that the casting choice takes them out of the story, or gets any unintentional laughs. So can a unconventional choice pull it off, and make it different? Thanks.
