The curse of Different Strokes continues .... RIP Gary, you will be missed!
The curse of Diffr'nt Strokes (I know Different was spelled poorly) is far reaching, especially for Coleman. Sure, a lot of 1980's sitcoms had a seedy underbelly of discontent... I read stuff about ALF that was kinda disheartening... but at least ALF was a really fun show.
Gary's life was absolutely ruined by that show (as were several of the other actors), making it impossible for him to get any work that didn't use him for camp value. And anyone in that situation would be decidedly frustrated. Sure, Batman made Adam West a star, but it was hard to find work after that, and he was often type cast. Bela Lugosi had to spend the rest of his career after Dracula making terrible horror movies. It happens, and it's a very unfortunate thing about fame... and again, it goes far back as Bela Lugosi.
It's really a shame he passed on too early, due to his condition he has since childhood. At least we can all say he's at peace now. Especially since he became a joke for most of his life.
