Nickelodeon has unveiled the first trailer for Hey Arnold! The Jungle Movie. While it's definitely a nice boost of nostalgia, despite noticeable updates to the voice cast and animation style, the trailer falls into the all-too-common trap of giving away far, far too much of the story. Keep that in mind before taking the plunge.

Co-written and executive produced by the TV series’ original creator Craig BartlettHey Arnold!: The Jungle Movie will answer the question of what happened to Arnold's parents. To do this, the movie will take the kids of P.S. 118 on a field trip to the jungle where adventure (and romance) awaits!

It also features original voice cast members Francesca Marie Smith as Helga and Anndi McAfee as Phoebe, alongside dynamic new voice talent Mason Vale Cotton as Arnold and Benjamin “Lil’ P-Nut” Flores, Jr. as Gerald. Lane Toran (original voice of Arnold) and Jamil Walker Smith (original voice of Gerald) will supplement the returning cast by lending their voices as Che and Paulo, two members of the boat crew in San Lorenzo, and Alfred Molina stars as resident villain, Lasombra. The movie arrives on Friday, November 24th in primetime over the Thanksgiving holiday.
