David Schwimmer wanted to "hide" after finding fame

He told the Hollywood Reporter: "It was pretty jarring and it messed with my relationship to other people in a way that took years, I think, for me to adjust to and become comfortable with. As an actor, the way I was trained, my job was to observe life and to observe other people, so I used to walk around with my head up, really engaged and watching people.

"The effect of celebrity was the absolute opposite: it made me want to hide under a baseball cap and not be seen. And I realised after a while that I was no longer watching people; I was trying to hide. So I was trying to figure out: How do I be an actor in this new world, in this new situation? How do I do my job? That was tricky."

Meanwhile, David previously admitted he found fame "painful".

He said: "I remember very well when celebrity first came to me. It was not something that made me comfortable. It was almost painful. I didn't like being treated differently than who I was.

"I just didn't respond well to it. I didn't understand why people were treating me as if I were special. I found that painful because I hadn't changed. I didn't like the idea that someone could suddenly get special treatment for doing nothing other than being on TV."
