John Noble

Was aviation pioneer Charles Lindbergh an American Nazi? Did a Hungarian musician's song trigger 18 suicides? How did a lobotomy doctor earn the Nobel Prize? Fringe star John Noble answers those, and some even creepier questions, as the host of Science's Dark Matters: Twisted But True.

Dark Matters returns for its second season Saturday at 10/9c. "I'm much more fearful of what I don't know than what I do know," Noble says. "We're not Mythbusters, but we've looked at events that people only shadily know of or perhaps have heard about, and reveal answers."

Noble says the show doesn't take these questions lightly, but still has a bit of a tongue-in-cheek element to it — starting with his presentation, which Noble says was inspired by Orson Welles. "I hope it's got a twinkle in its eye," he says.

Noble says researching his role as Walter Bishop on Fringe has also given him a unique perspective into some of the topics explored on Dark Matters. "Some of the CIA investigations we look at I have studied because, in a sense, Walter Bishop was in that era," he says, "and I have always played up the idea that Walter was funded by that CIA group back in the '70s and '80s." And just like Fringe, Noble believes that the unusual tales on Dark Matters will both entertain and fascinate viewers.

As for the upcoming farewell year of Fringe, which goes into production soon after Comic-Con, Noble calls the opportunity to do one final season a "gift." He adds: "It gives my complex character a chance to complete his arc."
