Backstreet Boys, *NSYNC, 98 Degrees and O-Town boy band members have collaborated on a song to promote their new movie. Nick Carter and A.J. McLean of Backstreet Boys fame have teamed up with *NSYNC hunks Joey Fatone and Chris Kirkpatrick to record single 'In The End' for their Syfy channel zombie movie, 'Dead 7'. The 90s boy band stars, who include O-Town's Erik-Michael Estrada and 98 Degrees' Jeff Timmons, all appear in the movie, which Nick helped to write alongside the makers of 'Sharknado'. Nick, 36, admitted the project is "pretty crazy" but is hoping the group's fans will unite to listen to the song and watch the upcoming film, which airs on April 1. He told BuzzFeed: "Think about it. Boy-banders, people from the late '90s, people who you love, fighting zombies in a post-apocalyptic world. Pretty crazy, right?" The two-hour TV movie is set in the post-apocalyptic West, following a group of gunslingers trying to rid a small town of a zombie plague. Speaking previously about the project, Nick said: "It's a zombie Western futuristic horror movie. "I want it to be musically based. I might reach out to Jordan [Knight] from the New Kids on the Block." *NSync's Joey said: "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 '90s and 2000s."
