Newsbusters caught this bit from his recent interview with James Cameron:

CHRIS MATTHEWS: I’m worried about the media though. Because now we have a right wing media available. That if you feel like, if you’re a business guy for example or a business woman and you want to have a good excuse, a good dodge not to do anything, well you listen to someone on the right like Beck who’s willing to come in and say, “Oh you don’t have to do anything. These guys are a bunch of tree huggers forget about it.”
JAMES CAMERON: Right. Yeah.
MATTHEWS: What do you think of Beck’s power in that direction, to give people a big excuse slip not to do anything?
CAMERON: Well guys like, like Beck and others and I think we all know-
MATTHEWS: Are they dangerous?
CAMERON: I think they’re very dangerous to this country. And I think some day they’re gonna have to answer to my children and to your children and their children for the world that they’re helping to create right now.
