12 Actors You Probably Forgot Were On Heroes
9. Seth Green & Breckin Meyer
Who They Played: Comic book aficionados Sam and Frack in Season 3's two-part The Eclipse.
Where You Know Them From: The apparently ageless Seth Green has been in everything from Buffy The Vampire Slayer to the Austin Powers series and Meyer, too, has appeared in a number of films and television, most recently as the first half of TNT's Franklin & Bash. The two also continue to gift the world Robot Chicken.
Why You Forgot They Were On Heroes: With Hiro and Ando on the hunt for a 9th Wonder! comic to guide them on their journey, Sam and Frack helped point both in the direction they'd been seeking. Sam helped inspire Hiro to rise up from his doldrums and informed Ando of the existence of the deceased Isaac Mendez's sketch book.
Unfortunately, their fleeting appearance during the busy Season 3 meant the show left them in the dust pretty quickly.
