New Line has set a summer start date on the third installment of the Harold & Kumar Go To White Castle franchise, with the Warner Bros-based company about to hire a director, and seriously considering doing the film in 3D. The film is Christmas-themed, giving Warner Bros a nice R-rated holiday release for 2011 or 2012. The biggest significance is that the start date signals the return of Kal Penn, who put his career on hold to take the position of associate director of the White House Office Of Public Engagement. The politically conscious actor gave up a lot to take the job–his doctor character, Lawrence Kutner, was killed off from the Fox drama House–but it was done with the understanding that he’d commit to the position for one year. As to the idea of leaving a prestige D.C. post to reprise in a stoner comedy, well, a guy’s got to make a living, right? He’ll leave shortly.
