"X-Files": The 13 Most Surprising Guest Starsby IMDb-Editors | last updated - 03 Feb 2016
The “X-Files” revival has (so far) given us Joel McHale as a conspiracy theorist and Doug Savant as a mad doctor experimenting with alien DNA. In the show's original run, unexpected guest stars were as nearly as common as alien sightings and Scully autopsies. Here are some of the biggest names – from Burt Reynolds to Ryan Reynolds – who've ever appeared on the show, many of whom didn't get famous until long after their brush with the paranormal. – Sharon Knolle
Bryan Cranston ("Drive")
Long before he was cooking meth in New Mexico as Walter White, the future Emmy winner guest starred as a man who kidnaps Mulder and insists on driving west, convinced his head will explode if he doesn't. It proved a pivotal moment for both Cranston and writer Vince Gilligan, who later cast him as the lead in the award-winning "Breaking Bad."
Alex Trebek and Jesse Ventura ("Jose Chung's 'From Outer Space'")
This tongue-in-cheek entry from 1996 features the "Jeopardy" host and former wrestler-turned-governor as Men in Black. Ventura threatens to kill a man who claims to have seen a UFO while Trebek tells Mulder, "You're feeling very sleepy."
Jerry Springer ("The Post-Modern Prometheus")
The talk show host appears as himself in this quirky, black-and-white 1997 episode about a man called, "The Great Mutato," who looks oddly like Frankenstein. Although the episode ends at a Cher concert (where Mulder and Scully dance together), Cher is played by impersonator Tracey Bell.
Richard Belzer ("Unusual Suspects")
It makes perfect sense that the other most obsessive conspiracy theorist on television, Det. John Munch, would meet up with the brainy Lone Gunmen. Belzer, who played Munch on both "Homicide: Life on the Street" and "Law & Order: SVU," also appeared as Munch on "Arrested Development."
