RIP. He's had some odd but memorable roles. One of the weirdest was in one of the versions of "Alice in Wonderland". He and George (Norm!) Wendt were Tweedledee and Tweedledum.
What a kick in the teeth. Other than the kids themselves, his casting in Harry Potter is one they really had to get right to appeal to young kids on the big screen - a giant who you would want to be friends with and trust with your life.
