Glen Campbell's documentary, Glen Campbell ... I'll Be Me, is one worth owning. Thankfully, the James Keach-directed film is heading to DVD and VOD on Sept. 1, courtesy of Virgil Films.

Campbell's documentary is an emotionally-driven, true story about the singer's tour following his diagnosis with Alzheimer's. Campbell was told by doctors that he should prepare to quit playing music, but he did something vastly different, instead setting out on a year-and-a-half-long tour across America in 2011.

"The making of this film has been an exhilarating, joyous and inspiring ride. I attribute that entirely to the heroic spirit of Glen Campbell and his extraordinary family," Trevor Albert, the film's producer, says.

The film has created quite a buzz. When it premiered on CNN in June, 2.76 million people tuned in to watch — a record for the network. The main song from the film, "I'm Not Gonna Miss You," has also snagged a laundry list of prestigious award nods.

Glen Campbell ... I'll Be Me drops to digital retailers on Aug. 18 before its DVD release.

"The legacy Glen Campbell and his incredibly courageous family share in this film is one of the most important movies I have been blessed to have worked on," director James Keach says. "Glen Campbell ... I'll Be Me will forever inspire me as a filmmaker and a man. Glen is a real life hero on and off the stage."

Today, Glen Campbell is in a full-time care facility. His children, including daughter Ashley, have vowed to 'Do the Remembering' for him.
