How many takes do you do with your actors?

I try to get everything done in as few takes as possible. The most takes I have ever done is 8. I was talking to the guy who runs my production company, who has been doing this for 20 years and has an incredible body of work, and he was telling me a lot of the best performances he gets are between takes 15-30. That’s like David fincher or Stanley Kubrick level to me and quite frankly I’m scared of asking my actors to do that much. How many takes do you typically do? Does anyone here do more than 12 takes?
