MTV’s Scream reboot is bringing the mystery and chills weekly, and with the revamp comes a whole slew of new-to-the-franchise characters. If you’re not familiar with the new Scream characters, you better do your homework and take a look at charming up-and-comer John Karna who plays nerdy but cool Noah Foster. Noah is somewhat of an overachiever, a boy-genius, a wunderkind if you will, but John Karna brings charisma and charm to Noah, making him still approachable, and never intimidating. You might recognize Karna from a few feature comedies, Premature and Bindlestiffs, but up next for John regarding film is a role in Sugar Mountain, a taut Alaska wilderness set thriller starring Jason Momoa (Game of Thrones) and Cary Elwes (The Princess Bride, Saw). The thriller has an impressive pedigree and could be just the role for Karna to breakthrough from being a Scream king to being A-list. Until then, check out John Tuesdays on MTV, and check out this clip from Tuesday night’s episode featuring Noah below!
