Members of the Backstreet Boys, ’N Sync, 98 Degrees and O-Town star in Syfy’s post-apocalyptic zombie Western Dead 7, from the schlock specialists at the Asylum (Sharknado). It even includes a new boy-band supergroup theme song. The movie’s top three boy-banders:

1. Joey Fatone. With his ridiculous facial hair, Nick Nolte-style rasp and ever-present flask, ’N Sync’s Fatone is a hoot as perpetually soused gunslinger Whiskey Joe, easily the highlight of the mostly terrible movie.

2. A.J. McLean. Inexplicably dressed like a mime (white face makeup, white gloves, bowler hat), Backstreet Boy McLean really gets into the sadistic insanity of Johnny Vermillion, right-hand man to main villain Apocalypta (played by Mad TV’s Debra Wilson).

3. Nick Carter. The Backstreet Boy’s performance as an enigmatic badass isn’t particularly convincing, but as the mastermind behind the project (co-writer, executive producer, head of the Indiegogo crowdfunding campaign), he’s clearly a marketing genius for combining ’90s pop-music nostalgia with the current zombie mania.

Dead 7 April 1, 8 p.m., Syfy.
