Backstreet Boys and 'NSync are to collaborate on a zombie Western movie.

The American boybands were chart rivals in the late 1990s, but have officially buried the hatchet by agreeing to work on a new horror movie in partnership with the studio behind the 'Sharknado' franchise.

Backstreet Boy Nick Carter said: ''It's a zombie Western futuristic horror movie.

''My character is still being worked out right now, but I'm a good guy that's going to help save the day.''

Nick, 35, is set to write and star in the post-apocalyptic drama about a ''ragtag band of gunslingers'' fighting a zombie uprising, and he's revealed he's reaching out to a number of musicians to star in the movie.

He told Rolling Stone magazine: ''There's a wish list of people that I want.

''I want it to be musically based. I might reach out to Jordan [Knight] from the New Kids on the Block.''

However, 'NSync's Joey Fatone has warned against expecting Justin Timberlake to make an appearance in the movie.

He said: ''I'm the only NSYNC-er as of now, but you never know.

''Nick's vision is to bring some other people in that genre that have never really done a lot of film but that were in music in the Nineties and 2000s.''
