Kat Dennings (Nick and Nora's Infinite Playlist) has been added to the cast of Thor, according to Hollywood Reporter.  Her role has not been revealed, although Hollywood Reporter thinks it's someone who works for Jane Foster (played by Natalie Portman see “Natalie Portman in Thor”), while other sites believe Dennings will play Marcy Lewis, a college student who's interning with scientist Kate Spelling.

The most recent casting announcement prior to this one was the news that Idris Elba has joined the cast (see “Idris Elba Joins Thor Cast”).
