"For me … [having] the responsibility to give back to a country and a world that affords you a lot of opportunities is vital; it's a critical part of character," Ben tells ET's Chris Jacobs, referencing good friend George Clooney's ability

"Politics is a thornier thing. … I do have some strong beliefs, but they don't all hew to one side, and I think it can actually be hurtful to get too involved in politics, because what happens is you might like someone's movie but then you go, 'Well, I know he disagrees with my politics.' So that can be dicey. Some people choose to do it. I've chosen to do it at times. Others do not, and I don't begrudge either one their choice."
