The Life and Death of Peter Sellers2004

[Peter Sellers and Stanley Kubrick are riding in a limousine]

Peter Sellers:
Three character is enough. Three is a good number.

Stanley Kubrick:
You're being paid for four.

Peter Sellers:
You're stretching me too thin, Stanley. Who do you think I am?

Stanley Kubrick:
I think you're whoever I want you to be.

Peter Sellers:
Then who am I now?

Stanley Kubrick:
Peter, have you ever heard of Mutually Assured Destruction?

Peter Sellers:
Hum a few bars and I'll join in.

Stanley Kubrick:
It refers to when both sides in an atomic conflict are so powerful that if either side were to take action, it would inevitably result in the total annihilation of all concerned. I find this concept can be applied to many situations.

Peter Sellers:
You're a peculiar f***er, Stan.

[Peter gets out of the car and it is revealed that they're in a stationary car in front of a rear projection screen on a film set]

Stanley Kubrick:
Wait Peter... Peter...

Peter Sellers:
You've got no idea what it's like to be me.
