Damon's easygoing, sunny personality seems an odd fit for Bourne's tormented, haunted character, but then, Damon is an actor. "I have demons and stress like anyone else, but hopefully I've got them under control, and then I just let them out for work, which is always healthier," he says.
The actor has balanced high-profile projects and starring roles with smaller supporting roles in such arthouse films as "Che" and "Youth Without Youth."
"They're really cameos for friends, and I love doing that," he reports. "I was in Spain promoting the last 'Bourne' movie, and 'Che' was on such a shoestring budget while they were shooting (in Spain) that I managed to squeeze in a day's shoot for Steven in between interviews for 'Bourne.' And then Coppola called me about 'Youth' and talked about Ingmar Bergman and how he wanted a similar small ensemble of actors, and I told him I'd go anywhere to do it for him. So I flew to Bucharest for one day to do those few scenes."
