A new video released by Lionsgate takes you on the set of Texas Chainsaw 3D, the sequel to Tobe Hooper's original Texas Chainsaw Massacre. The B-roll features a lot of the cast, but what's interesting here is get you get a peek at "Grandpa," once again played by John Dugan. Other TCM vets include Gunnar Hansen and Marilyn Burns. Check out the video below.

Decades later and hundreds of miles away from the original massacre, a young woman named Heather learns that she has inherited a Texas estate from a grandmother she never knew she had. After embarking on a road trip with friends to uncover her roots, she finds she is the sole owner of a lavish, isolated Victorian mansion. But her newfound wealth comes at a price as she stumbles upon a horror that awaits her in the mansion’s dank cellars.

Alexandra Daddario, Tania Raymonde, Sue Rock, Scott Eastwood, Bill Moseley, Gunnar Hansen, Trey Songz, Keram Malicki-Sanchez, Shaun Sipos, Thom Barry, Paul Rae and Richard Riehle star in the January 4 release.
