Sam Jones followed up his role as Flash Gordon by playing Denny “The Spirit” Colt.
By the way, google insists that Knight Rider got an ongoing comic book describing the adventures of crimefighter Michael Knight and his Tony-Stark-esque gear – which arguably puts David Hasselhoff in the running (as, uh, the white Nick Fury).
Who was also not only Superman, but Dylan Dog to boot.
James Earl Jones: Darth Vader (Star Wars), Thulsa Doom (Conan the Barbarian)
Ron Perlman: Hellboy (Hellboy), Conan’s father (Conan the Barbarian reboot), Various voice acting roles (tons of animated series)

Robert Livingston was the Lone Ranger and Zorro, and was also mild-mannered church organist Don Loring – secretly The Masked Vigilante Known Only As The Eagle!
Jim Carrey: Somebody already mentioned Captain Stars and Stripes and the Riddler. He also played the Mask.
Mentioned in the same post.
Y’know, technically – technically – George Hamilton played both Zorro and Dracula.
Paul Bettany was in Priest (loosely based on a korean comic) and voices Jarvis in the iron Man/Avengers films
Also Blade II and the live-action Prince Valiant flick
John Hart played the Lone Ranger and Captain Africa (he was supposed to play the Phantom, but there were copyright issues).
He also played one of Luthor’s henchmen in Atom Man vs Superman, and a bit part in the 1949 Batman and Robin
You have proven me wrong, which of course means you don’t get any cookies.
Plus he was in Captain America as Colonel Phillips.
Excellent! I’ll have my lawyer write up the papers.
Before playing Bruce Wayne’s straight-out-of-the-comics butler, Michael Caine was a one-man League of Extraordinary Gentlemen as Captain Nemo, Jekyll/Hyde, and Sherlock Holmes; also playing Holmes – Sherlock and Mycroft – was Bond villain Christopher Lee, who before his Dooku days was Fu Manchu and Dracula when he wasn’t busy fighting Captain America in one movie and Captain Invincible in another.
Arnold Schwarzenegger was Conan the Barbarian, Mr. Freeze from Batman and Robin…and Turboman from Jingle All The Way;)
Robert Townsend was The Meteor Man on the big screen, and the superpowered Bronze Eagle in the Disney Channel movie Up, Up, And Away!
Which also gave a comic-book credit to a post-Obadiah-Stane Jeff Bridges.

Duncan Regehr was a Batmannish Zorro after playing a downright scary Dracula.
