Playing a plainer role means everything is dependent on the credentials of the actor, not the fact that they are as pretty as Julia Roberts. People start to look at their talent rather than their appearance. And playing the ugly part often means less time in the make-up chair, which is a great benefit on set.

In a way, it's good not to be recognised as much off screen.

We all have hierarchies at work - even on set, the runner would never walk up to the director and ask for a cup of coffee.

I think as an actor you're used to having to travel, so wherever the work, is you're willing to go.
