Seth Green has come a very long way since he was a child actor in the original TV movie version of 'IT.' It might be hard to put your finger on one particular film that he's appeared in, but he's a face you recognize from everywhere. Just as recognizable as his face is his voice, which he's lent to Chris Griffin on 'Family Guy' for years. His real pride and joy is 'Robot Chicken,' which may not have the rabid fan following of 'Family Guy,' but is adored by the cult audience it appeals to.
Perhaps if we saw Green in person more often rather than just hearing his voice, we'd be more likely to notice his height - or lack of it. Green is a mere 5 feet and 4 inches tall. We suppose that's the thing about voice acting though - you can play a seven-foot giant easily if nobody can see you!
