Who needs Washington when you can have White Castle? Kal Pennís reps confirm that the actor will leave his post as Barack Obamaís associate director of public engagement to return to his acting career. First up for the actor: a new Harold & Kumar movie, this one with a Christmas theme. New Line Studios has confirmed that the movie, to be directed by newcomer Todd Strauss Schulson, will begin filming in late June with an eye on a holiday 2011 release. The studio, now a division of Warner Bros., is still deliberating whether it will be shot in 3-D. Penn began his White House stint last year, shortly after his character on the television show House was abruptly killed off in April, per Pennís request to join the Obama administration.
