David Warner, who has been in a ton of stuff can be hard to spot until you hear him speak, if you only know him from Star Trek 6 and as Gul Madred.
He was both Chancellor Gorkon in Star Trek VI and St. John Talbot, Federation Ambasador to Nimbus III in Star Trek V. Hard to believe it's the same person. He was also MCP - the Master Control Program in Tron.
Don't forget that he played Jack the Ripper in Time After Time
against Malcolm McDowell's H.G. Wells. Trek alumni are all over the damn place.
