I like to rehearse with the actors scenes that are not in the script and will not be in the film because what we're really doing is trying to establish their character, and good acting to me is about reacting. ↗
But I think the other is a little more like bullfighting, a little more daring and although I appreciate good acting and I liked being versatile my whole career, it kept me working. ↗
The biggest mistake in student films is that they are usually cast so badly, with friends and people the directors know. Actually you can cover a lot of bad direction with good acting. ↗
