1) When speaking to an actor off-camera, look into one eye and stick with it.
2) Film acting is, in large part, reacting and listening.
3) While rehearsing something with a fellow actor, if a crew member can come up and recognise you’re rehearsing versus having a real conversation, then you aren’t doing it right.
4) An actor relaxes in front of the camera by concentrating and knowing that you have no enemies on set everyone’s on your side and doing their best to make you look your best for the movie.
5) The camera catches everything you do, so don’t be afraid to play things subtly.
6) If you’re going to smoke on-screen, you must plan it absolutely perfectly, don’t mess up the continuity.
7) All actors steal certain gestures and behaviours from other actors ,but the best actors make these gestures their own. Steal from the best, and make it your own.
8) You can make four pictures as an actor in the time it takes a director to make one ,so if you’re an actor planning on becoming a director, consider the financial aspect.
9) A majority of movie acting is relaxation. If you’re knocking yourself out, you’re doing it wrong.
10) Theatre acting is an operation with a scalpel, movie acting is an operation with a laser.
