Todd Bridges on Gary Coleman: ‘He Wasn’t Prepared’

Todd Bridges and the late Gary Coleman were inseparable during their "Diff'rent Strokes" heyday in the late '70s and early '80s, and now "Willis" gets serious with ET's Kevin Frazier as he recalls Gary's good times, struggles and secrets.

"We had an exceptional time as kids," says Todd, who played Gary's big brother on the show. "We always had fun in our dressing rooms, we'd always roller skate together around [the studio lot], we always hung out … we went to school together. He was a precocious, fun little kid that was very bright for his age."

Todd explains the foundation behind Gary's sometimes cantankerous behavior, saying, "Imagine having major health problems. Imagine getting ripped off of all your money. Imagine being raised in a household where he wasn't taught how to love himself or to love others around him. So when he hit the world at an adult age, he wasn't prepared."
