""I was always open to doing it with (director) Paul Greengrass and they never had a script... What happens in these big budget movie is they'll get a release date and they'll book everybody's time and they'll just send you off to a location with no script and that's your problem and you've gotta figure it out... I didn't want to put myself in that situation again because that takes years off your life."" Matt Damon on turning down the latest Bourne franchise movie.
