Another deal has gone down for a 2017 Sundance Film Festival title ahead of the festival's opening on Thursday — and this one comes with a "Touch of Grey."

Amazon Studios has acquired "Long Strange Trip," a four-hour documentary profile of the legendary rock band The Grateful Dead. The movie is directed by Amir Bar-Lev ("The Tillman Story," SFF '10) and produced by Martin Scorsese.

The movie will debut on Amazon Prime in the United States and United Kingdom on May 26, as a six-part documentary.

"Long Strange Trip" will premiere Monday at 8:30 p.m. at the Yarrow Hotel Theatre in Park City. Grateful Dead members Mickey Hart, Bill Kreutzmann and Bob Weir will be on hand for the screening, along with Trixie Garcia, widow of Jerry Garcia.
