It would seem James Gunn has drafted his old pal Nathan Fillion (Serenity, Slither) in for an appearance in Guardians of the Galaxy Vol. 2, playing none other than Simon Williams, aka Wonder Man. In the comics Williams started out as a villain before putting his wicked ways behind him and joining The Avengers. He later retired to pursue and acting career, which is referenced by these mock movie posters that were sent to Comicbook.com. Whether Fillion actually shows up onscreen as Williams in the movie or not remains to be seen of course, as there’s every chance these posters will just be used as background easter eggs. Still, pretty cool I’m sure you’ll agree. Set to the all-new sonic backdrop of Awesome Mixtape #2, Guardians of the Galaxy Vol. 2 continues the team’s adventures as they unravel the mystery of Peter Quill’s true parentage.
