The Broken Arrow star signed up for martial arts lessons in a bid to get over the lifelong inadequacy he felt over his lack of height and discovered he had a knack for "kicking butts".

Slater says, "They (teachers) definitely didn't cut me any slack in there. We were all kicking each others' butts - it was great.

"Also, I wanted to introduce my son to it. He was about three, and I thought, 'Well, this is cool. He can go and watch me.'"
