The Neighbors 3: Zombies Rising short film pitted Seth Rogen and Zac Efron against the undead, but will this fun pitch ever becoming a full movie? The original Neighbors from 2014 found a couple having to deal with the fraternity that moves in next door to them. In addition to being a fun comedy, Neighbors was also a showcase for Efron as the party obsessed dudebro who secretly hides a lot of insecurity.
Buoyed by the movie's surprise critical and commercial success, Rogen and his creative partner Evan Goldberg put together the first sequel based on their own project with 2016's Neighbors 2: Sorority Rising. The sequel found the couple from the first movie, Mac and Kelly, having to deal with the sorority that moves in next door, led by Chloe Grace Moretz. Mac and Kelly turn to Efron's Teddy for help in their new war.
Neighbors 2 ends on a happy note for the main characters, but while promoting the film, Rogen and Efron shot a short film dubbed Neighbors 3: Zombies Rising to promote the project. This brief teaser finds Mac and Teddy arguing over how to deal with a tied up zombie, with matters becoming complicated when Teddy realizes the zombie was once part of his fraternity. The short ends with Rogen and Efron discussing what a great idea it would be for the third movie.
Neighbors 3: Zombies Rising was a bit of cross-promotion between Sorority Rising and Fear The Walking Dead, with the short debuting during an episode of the latter. While Zombies Rising was only ever intended as a fun advert, fans quickly saw the potential in a third movie where Mac and Teddy try to survive a zombie apocalypse together.
Unfortunately, not only is Neighbors 3: Zombies Rising unlikely to happen, Seth Rogen has essentially sworn off sequels in general. Despite receiving good reviews, Neighbors 2 grossed less than half of the first film. Rogen and Goldberg also prefer to work on new ideas, meaning sequels to Sausage Party or This Is The End probably won't happen either. The duo ruled out making blockbusters again after a bad experience making Green Hornet and that's a vow they've stuck to.
That said, This Is The End originally came from a 2007 short called Jay And Seth Versus The Apocalypse, so maybe Rogen will return to the idea of a buddy team-up between him and Efron against zombies in the future, even if it's not a direct sequel. For now, there doesn't appear to be any plans for Neighbors 3: Zombies Rising and while it would probably be a lot of fun, Rogen and Goldberg swearing off sequels makes the odds of it happening very slim.
