Stargate SG-1 Cast: Where Are They Now?

21. Peter Williams

Stargate Apophis

Peter Williams was Apophis, the evil Goa'uld who was the primary antagonist for much of the early years of Stargate SG-1. While he was thoroughly defeated in the show's fourth season, Williams appeared in guest spots for the rest of the show's run, even up to the final film, Continuum.

A Jamaican born actor, Williams had previously appeared with Richard Dean Anderson in MacGyver. After his tenure on SG-1 ended, he would go on to appear in such films as Catwoman and The Chronicles of Riddick, though most recently he has appeared in The Expanse.
