More boyband stars join zombie Western film written by Backstreet Boys’ Nick Carter

However, One Direction's Niall Horan appears yet to accept an offer to appear in the film

Another two boyband stars have joined the cast of Dead 7, the “zombie Western” movie written by Nick Carter from the Backstreet Boys.

Carter is starring in the film alongside his Backstreet Boys bandmates Howie Dorough and A.J. McLean, plus Joey Fatone of similarly popular ’90s boyband ‘NSync.

A plot synopsis for the film – which is being made by production company The Asylum, best known for the so-terrible-it’s-entertaining Sharknado franchise – teases: “Dead 7 is the story of a ragtag band of gunslingers who must rid a small town of a zombie plague in a post-apocalyptic West. Nick Carter will play Jack, the reluctant hero who unites the outlaws to face the zombie menace.”

Last month Carter tweeted at One Direction’s Niall Horan asking him to play his brother in the film, but Horan seems to have resisted the offer so far. However, photos from the film’s set shared on Instagram recently show that Jeff Timmons of 98 Degrees and Jacob Underwood from O-Town have both signed up for roles.

When Dead 7 was announced in late July, David Michael Latt of production company The Asylum said the film was already sparking interest in Hollywood. “What [Nick Carter] came to us with was a big idea of pop music stars in a genre setting. A lot of the platforms, distributors and companies we work with responded to that immediately and we knew we had something we should move forward with,” he explained.

Meanwhile, Joey Fatone has said that the film should help to dispel rumours that Backstreet Boys and ‘NSync were rivals during their ’90s chart heyday. “We’ve never done anything together collectively. People always think [we’re] some sort of rivals. But it’s so funny – there’s never been animosity or anything like that. Now we’re setting the record straight by doing a film together,” he said.
