EXCLUSIVE: Big Time Rush’s lead singer Kendall Schmidt is taking a solo sabbatical, and the results will be turned into a feature documentary he’ll make with producer Garret Grant. Grant — whose credits include Hairspray, Rock of Ages and Justin Bieber: Believe — will join Schmidt on his upcoming debut tour with solo band Heffron Drive, which takes Schmidt through 20 major cities throughout November and December. Schmidt is the first of the current boy band stars to go solo, and though he’ll make himself available for Big Time Rush reunions, putting the results on film is a way for him to broaden his horizons.

“It’s awesome to have Garret along to document this crazy time in my life,” Schmidt says. “It’s scary, it’s new, but it’s a really special moment, debuting Heffron Drive, heading out on tour and reuniting with all the amazing fans. It’s all I’ve ever wanted.”

The 23-year-old, who grew up acting, is taking his film ambitions further. With partners and producers Rob Minkoff, manager Michael Cammarata and brother Kevin, Schmidt will be part of the animated film The Great Migration. He’ll be joined by Vanessa Hudgens, Ashley Tisdale and Ashley Benson. That group will voice the lead characters and score the original soundtrack. They expect to start production in the winter and release the film through the newly formed CMI Entertainment group.
