Heroes Reborn actor Marco Grazzini has been cast as Tar Pit for the Flash (EXXXCLUSIVE via ComicBook). The character was part of the "new" Rogues created by Geoff Johns and Scott Kollins on their run on the book. He'll of course be different then his comic book counterpart given he's literally walking molten asphalt. Instead, he'll be able transform into molten asphalt (to save that budget for where it counts like giant talking Killer Sharks and Gorillas).
The episode will sometime air when the Flash returns in February for all-new episodes. Speaking of which, the show will air its mid-season finale next week with the return of Mark Hamill as the Trickster!!! Yes, yes it's going to be glorious! GLORIOUS!!
