Neil Patrick Harris (the actor and the character) is returning for the third installment of the Harold and Kumar trilogy. Harris joins the original stars, John Cho and Kal Penn, as well as newcomers Patton Oswalt and Thomas Lennon.

The film, currently titled A Very Harold & Kumar Christmas, has already begun shooting at a mall in Michigan. Unfortunately, it’s not slated for release until Christmas of 2011. If that bums you out, just get stoned, click here, and forget I said anything. (Empire Online)

Harold & Kumar 3 began filming today in a mall in Michigan, and the cast and creators are tweeting about their adventures. John Cho, the Asian in the dynamic cannabis-loving duo had this to say: "In Michigan, @pattonoswalt in my vicinity, holding a sketch pad, duct tape, and a reel to reel audio recorder. Eeesh." Whoa, so Patton Oswalt is on set too?! Oswalt tweeted: "Maybe it’s this Michigan air, but @JohnTheCho is looking huggable, chloroform-able, and bury-able."

As much as I’d love Oswalt being there to star in the movie, I gather by his tweet that he’s simply hanging around set to chloroform, rape, and murder John Cho. He didn’t specifically say "rape" but chloroform isn’t used for much else these days. And since Kal Penn didn’t chime in on Twitter, he must already be under floorboards somewhere.

Check out some pics from the set after the jump…
