A great actor is a combination of two things: talent and technique.
When you have a person with enormous talent and you provide them with a great technique, that’s what makes a great actor.
What you bring to the table is your talent.
[Acting teachers and coaches] provide technique.
Marlon was a great actor because everything he did was unpredictable yet, in the end, inevitable.
That’s my definition of [great] acting.
