The Backstreet Boys and ‘Nsync are teaming up to fight zombies in the Old West. That’s the elevator pitch for a project in the works from Nick Carter. And he’s bringing along friends.

There is a little more to the tale, of course. And although some of the Backstreet and ‘Nsync members are signed on, not everyone has been brought on board … yet. So far, Nick Carter has roped in fellow Backstreeter Howie D, as well as Joey Fatone and A.J. McLean from ‘Nsync.

“We’ve been friends for a long time,” Nick said of his boy band connections. “I knew this would be a fun thing for us to do.”

“I wanted my friends in the film with me. What is more fun than riding horses and being zombies, shooting things? Even as a kid I loved horror films, this was always something I wanted to do. How cool would it be to have boy banders fighting zombies?”

Carter explains the evolution of the film project, called Dead Seven, which is set to air on SyFy.

“I started writing this screenplay, [originally called] Dead West, close to five years ago but it wasn’t till about two years ago that we really started to make it happen. It was first called Dead West but was told that could be too limiting, wanted to make it more modern and apocalyptic than an old western. They use zombies to control the post-apocalyptic town and the 7 bandits basically come in and save the day,”

With a more evolved concept, Carter and his boy band friends were off and running. But they don’t intend to go it alone.

A.J. will play a villain, Joey will play a drunk, and Howie D will be play a “Latino gunslinger.” But this film has the same money from Sharknado behind it, so that means celebrity cameos are the order of the day. Nick Carter has been busy recruiting.

“I get into these moods and just feel like asking,” Nick said. “You never know until you ask.”

The celebs he’s asked so far include Sisqo, Paul McCartney, One Direction’s Niall Horan, and Spice Girl Melanie Brown.

But what about the rest of BSB? Carter says Brian Littrell and Kevin Richardson are interested.

These guys need to do get Jimmy Fallon in on the action. That’s the surest way to get Justin Timberlake on board.
