A documentary on the life of out actor George Takei opens in limited theaters, on iTunes and other on demand sites on Friday.

To Be Takei premiered to wide acclaim at the 2014 Sundance Film Festival in Park City, Utah.

The film, directed by Jennifer Kroot (It Came From Kuchar), takes a look at Takei's journey from spending part of his childhood in a World War II internment camp to manning the helm of the Starship Enterprise. After publicly coming out gay in 2005, Takei married his partner Brad Altman in California and went on to become an LGBT rights advocate.

Star Trek co-stars appearing in the film include William Shatner, Leonard Nimoy, Nichelle Nichols and Walter Koenig.

The film ran exclusively on DIRECTV through August 5.
