It’s with sadness that we mark the passing this week of one of the unsung heroes of the B-movies — Mr. Treat Williams. Here are six of his movies that left a mark with his good-natured action star charm:

Star Wars: The Empire Strikes Back (1980) — Echo Base trooper Jess Allashane and Cloud City trooper Jerrol Blendin

Dead Heat (1988) — Detective Roger Mortis

Things to Do in Denver When You’re Dead (1995) — “Critical” Bill

The Phantom (1996) — Xander Drax

Deep Rising (1998) — John Finnegan

Gale Force (2002) — Sam Garrett
