Ellen DeGeneres, Neil Patrick Harris, Suze Orman, Cynthia Nixon, Janet Mock and Wanda Sykes are among those featured in HBO's upcoming documentary The Out List.

The film, which has been making the rounds on the LGBT film festival circuit, will premiere on premium pay network HBO on Thursday, June 27, the 44th anniversary of the Stonewall riots. The film will have its Miami premiere on Friday, June 21 at the Gusman Center for the Performing Arts.

The documentary is from Timothy Greenfield-Sanders, portrait photographer and director of About Face: Supermodels Then and Now, The Black List and The Latino List, and interviewer Sam McConnell.

Greenfield-Sanders told Vanity Fair that the film was originally going to be called Generation 8, a reference to California's gay marriage ban, Proposition 8.

“We started to interview people and we felt it would be limiting to be just about marriage equality; there are so many other issue,” he said.

Also sharing their experiences in the movie are Dustin Lance Black, Lady Bunny, Clarke Cooper, Wade Davis, Twiggy Pucci-Garcon, Larry Kramer, Christine Quinn, Jake Shears, Wanda Sykes, Lupe Valdez and Wazina Zondon.
