Football head is back.

The trailer for the upcoming Hey Arnold! The Jungle Movie has just landed - and it's definitely making us nostalgic. The newest instalment of our favourite 90's cartoons sees the kids of P.S. 118 try to figure out one of the show's biggest mysteries: what exactly happened to Arnold's parents? The pals will all head to the fictional South American country of San Lorenzo as part of a school trip after winning a competition - before setting out to solve the mystery. And, of course, just about everything we've missed about the show will be back - including Helga's secret Arnold shrine. The movie will pick up where the series left off, aiming to tie up some of the loose ends from the show - as well as serving as the definitive series finale. And the film, due to premiere on Nickelodeon on November 24, could lead to more football head in the future. According to Polygon, voice actress Olivia Hack, who played Rhonda Wellington Lloyd on the show, said:

“It’s resolution but not closure. “Our goal is to go to series after this. We’re hoping that’s what happens.”

Most of the original cast and crew have gotten involved with the film. The original voices for Arnold and Gerald aren't back in the same roles - but they will be appearing as other characters in the movie. Meanwhile, the actors for Helga, Phoebe, Harold and Grandpa - among many more - are reprising their original roles. Hey Arnold! first premiered as a television series in 1996, and ran for five seasons.
