Anyone else get as excited about trailers as the actually movie??? It's an art! In this case it's the trailer for a music documentary. Backstreet Boys fans are just a bit breathless over the trailer for the upcoming documentary Backstreet Boys: Show Em What You're Made Of. It opens with a throwback montage of A.J. McLean, Howie Dorough, Nick Carter, Kevin Richardson and Brian Littrell at the peak of their fame in the late '90s, and then leaps to present-day with Littrell asking, "What do you do when you're a full-grown man in a boy band?" The doc is in theaters January 30th, 2015.
