Backstreet Boys And 'NSYNC Are Finally Banding Together….To Fight Zombies

And they are inviting Niall Horan along for the ride.

Finally! After 20 years the Backstreet Boys and 'NSYNC are coming fight zombies.

That's right. BSB member Nick Carter is set to write and star in the upcoming western zombie film "Dead 7." The boy bander started writing the script seven years ago, as an old wild west horror film, but when he brought it to The Asylum (best known for the "Sharknado" franchise), they decided to give the story "a little more modern" twist with the addition of zombies and a post-apocalyptic setting.

"It's after the world has ended...there's zombies everywhere and people have to leave the big city and re-inhabit the western town to get away from the plague," Nick told us. "There's this shaman that's tormenting the town and using zombies as a weapon to control this small town."

To help stop the zombies, Nick, who portrays the story's protagonist, Jack, teams up with a former musical rival and IRL friend, 'NSYNC's Joey Fatone. "We actually share a lot in common -- I get Joey, I get his humor and how he is and when I called him up it wasn't very difficult to rekindle that friendship," Nick said.

Still, saving the day won't be easy, with Nick's fellow boy band member A.J. McLean as the "cool villain" standing in their way. (BSB's Howie Dorough stars in the flick as well.)

As for the rest of the cast? Well, be on the lookout, because it's shaping up to be a '90s pop party filled with some of your favorite throwback artists.

"There are so many different people that want to come on board, a lot of singers, and people that were not just in boy bands, but singers in the late '90s," Nick explained. "Most people as an artist, as an entertainer, a lot of them love acting, but they haven't had the shot or the chance to do that because they are too busy or whatever other reasons, but this movie gives them the opportunity."

And Nick has a big wish list. He's reached out to Sisqo, who did say he was "interested;" Melanie Brown, a.k.a Scary Spice; and even One Direction's Niall Horan, whom he'd love to portray his "younger brother who is basically dating my former girlfriend."

Unfortunately, Niall hasn't gotten back to him yet, but if that doesn't pan out, Nick's holding out hope that Jesse McCartney will fill that younger brother role.

"I had this idea of creating a cast that is so abstract and is so outside of the box when people are flipping through it on Netflix, they are like, we have to watch that," he said. "We need to twist things up, we need to mix things up and create something that is not the same old cookie cutter."
