Warner Bros. has released a new red band trailer for A Very Harold & Kumar Christmas.  The sequel takes place six years after Harold & Kumar Escape from Guantanamo Bay---the duo has grown apart, but when Kumar decides to bring a mysterious package to Harold's house, Kumar inadverdently burns down Harold's father's prized Christmas tree.  In place of White Castle, the stoner quest at the center of Christmas is to replace the tree.John Cho and Kal Penn return as the title characters, joined by Neil Patrick Harris, Patton Oswalt, Thomas Lennon, Danny Trejo, Eddie Kaye Thomas, David Krumholtz, and Elias Koteas.  A Very Harold & Kumar Christmas opens in 3D on November 4th.  If you're over 17, watch the red band trailer after the jump.The Harold & Kumar sense of humor is at home with the red band format, so be warned that the trailer is wildly NSFW.  It looks like director Todd Strauss-Schulson (new to the series) had a ton of fun with the 3D element.  All sorts of gimmickry flies out of the screen in these two minutes: fire, glass, a tooth, a blunt, a Claymation penis.For comparison, watch the green band trailer here.  Red band trailer via IGN:I don't know what this says about me, but a baby high on marijuana, then cocaine?  Hilarious.Official synopsis:

The new “Harold & Kumar” comedy picks up six years after the duo’s last adventure. After years of growing apart, Harold Lee (John Cho) and Kumar Patel (Kal Penn) have replaced each other with new best friends and are preparing for their respective Christmas celebrations. But when a mysterious package arrives at Kumar’s door, his attempt to deliver it to Harold’s house ends with him inadvertently burning down Harold’s father-in-law’s prize Christmas tree. With his in-laws out of the house for less than a day, Harold decides to cover his tracks rather than come clean, and reluctantly embarks on another ill-advised but hilarious journey with Kumar, taking them through New York City on Christmas Eve in search of the perfect Christmas tree.
