"The trouble with talking about acting is that it's like sex. It's enormously fun to do but just dreadfully embarrassing when you have to talk about it"

In this quote, star Paul Bettany compares talking about acting to speaking about sex. He suggests that both activities are satisfying to do, but when it concerns discussing them, it can be rather uneasy and uncomfortable. This might be due to the fact that both acting and sex are deeply personal and intimate experiences that are tough to take into words. Bettany's use of the word "awkward" suggests that there is a specific vulnerability in going over these topics, as they reveal a lot about oneself. In general, this quote highlights the intricacy and sensitivity of both acting and sex, and the obstacles of trying to articulate them.
