20 Actors You Totally Forgot Were In Comic Book Movies
15. Seth MacFarlane
The Movie: Hellboy II: The Golden Army (2008)
Who He Played: He voiced the by-the-book ectoplasmic BPRD agent Johann Krauss, who set aside his differences with Hellboy and ultimately resigned alongside his colleagues in the final moments of the film.
Why You Forgot: With each passing year making Hellboy 3's prospects look dimmer and dimmer, the franchise hasn't had the chance to continue growing on the big screen. Though Krauss was a great addition to the sequel, many casual viewers probably didn't even realize it was MacFarlane - the man behind Family Guy, American Dad, Ted and its upcoming sequel, among other things - loaning his vocal talents in the first place.
