Mostly famous for plugging Quaker Oats in the Eighties, Wilford is remembered best as being the scientist in The Thing who knew how dangerous the doppelgänger monster was. After the John Carpenter remake, I would have to go with Cocoon, the light-hearted Sci-Fi flick Ron Howard directed. I guess Wilford just was able to play old and grumpy since he would’ve been around 50 during Cocoon yet the main characters were supposed to be Florida retirees.
He did do a bunch of other movies and TV but the only remaining thing coming to mind I would vaguely remember would be The China Syndrome.
Thanks for your contributions Wilford! It’s a good thing you didn’t need to convince me to enjoy oatmeal, I had that one down as a little kid.
