After a while, the character sort of took over.
George Lucas puts those types of characters in for the kids. Same with Jar Jar.
George has only got to ring me. His imagination is so wonderful, I'd do any character he might create.
It was amazing that during rehearsals, without any of the costume on, the character was there complete. It just happened. Half the time, I didn't know I was doing it.
I think by that time I knew where Chewie was going, and he left me to do what was called for, because the character had been well established. You know, it was like putting on a second skin by that time.
Then I put on the new suit they'd made and it felt wonderful to climb back into it and feel the character coming back out again.
