Every role is challenging in its own way, but the most challenging roles are the ones that are badly written - then it's completely up to you to come up with something that is interesting to the story and myself as an actor.

I remember the day Richard Nixon won in 1968. That was a time that seemed certain to bring about long awaited seismic change in America. But events of tragic proportion took us on a turn. Bobby Kennedy and Martin Luther King, Jr. were suddenly dead.

I've been very lucky not to have turned down too many roles that I've later regretted.

My parents grew up in the Depression. Despite the success that they both had in their lives, there's a certain mentality that tells you to finish all the food that's on your plate and not wasting anything and appreciating what's on the table.

I was doing a play out in L.A. 20-some-odd years ago called 'Goose and Tomtom' by David Rabe, and somebody saw it and the next thing I know I'm doing the table read of the film version of 'Glengarry Glen Ross' with Al Pacino and Jack Lemmon - one of the great films of our generation.
