The 2 Broke Girls star is coming back to hang out with the God of Thunder. Kat Dennings will reprise her role as Darcy Lewis for Thor: The Dark World. While details are scant for the Marvel Studios’ sequel, it does seem that Dennings’ role has expanded from that of the comic relief sidekick she played to Natalie Portman in the first Thor. But then a lot has changed for Dennings since Thor came out in May 2011. For one thing, she is now on one of the hottest sitcoms on TV. Since its September 2011 debut, 2 Broke Girls has been one of the highest rated new series this season.
