With 'Taxi Driver,' I had this eureka moment. I realized that acting could be much more than what I had been doing. I had to build a character that wasn't me.
It was a weird moment in my life and a weird experience [doing a theater]. It made me think, "Gee, I don't know if I ever want to do this again." And I love theater. I love going. I love the experience of theater. But I am not sure it's for me.
I think it works better with a woman, which is why I decided to do it, ... men know how to separate themselves from their child. Women lose that ability.
