During a promotional interview with MTV for new film Brothers (directed by six-time Academy Award nominee Jim Sheridan) Natalie Portman revealed that Kat Dennings (Defendor, The 40 Year Old Virgin) will be joining her onscreen in Kenneth Branagh’s live-action adaptation of Marvel’s Thor. When asked about the upcoming production, Portman said:

“Well I’m really excited. Kat Dennings is going to be in it with me and she’s a good friend and an amazing actress, so I’m looking forward to that.”

Dennings is the fifth new cast member revealed to be joining Thor in the past six days along with Idris Elba, Tadanobu Asano, Ray Stevenson, and Stuart Townsend. Unlike the others however, the character she will play has not yet been announced.
