Best known for: Clay Marrow, Sons of Anarchy (FX)
Weirdest role: Amoukar, The Quest for Fire (1981)

Have you ever looked at fire and thought, "Damn, I need a movie about how they came up with that"? If so, it's your lucky day, and you should cut back on the narcotics. The Quest for Fire, a Canadian/French/American co-production, had many quirks, including dialogue delivered in an invented language and associate producer who only handled "animal and action scenes." Despite the film's strange elements, The Quest for Fire made back four times its budget and won widespread critical accolades while beginning Ron Perlman's thirty year love affair with prosthetics. He got hairy.
