The official trailer of US band Backstreet Boys's upcoming documentary "Backstreet Boys: Show Em What You're Made Of" has been released on the internet.
The two-minute trailer opens with a blast from the past montage of A.J. McLean, Howie Dorough, Nick Carter, Kevin Richardson and Brian Littrell at the peak of their fame in the late 1990s, and then quickly goes to present-day with Littrell asking: "What do you do when you're a full-grown man in a boy band?" reports eonline.com.
"Backstreet Boys: Show 'Em What You're Made Of" hits theaters and iTunes on Jan 30 next year.
