Of all the actors who have ever been in a WC production I have notice Pliers the most in mainstream Hollywood features. And as Said "Flash" seems to be getting alot of bigger roles lately. "Hawk" and "Deker" show up in a bunch of action movies.
Hawk is probably best remembered as Hank Jennings from Twin Peaks and Decker had a re-appearing role on Hercules and Xena.
Hamill is in plenty of good movies. "Batman Beyond: Return Of The Joker" stands out as does "Walking Across Egypt". Just stay away from "Watchers Reborn".
You might be thinking of McDowell on the show "Pearl" back in 96.
