The movie was written by Lena Waithe and shot by Beyonce Knowles's Formation music video director Melina Matsoukas, and their celebrity friends have been rallying support for the project on social media to celebrate its U.S. release this week.
On Friday, November 29, Beyonce's best pal and Destiny's Child bandmate Rowland joined forces with her husband, Tim Weatherspoon, to buy out two showings of the project in her native Houston, Texas.
As she invited members of the public to attend the screenings, Rowland explained she wanted to put on the events "Because it's a GREAT film, and because it's made by two incredibly talented WOMEN!"
Big Sean also got behind the movie, and offered up free tickets for a screening in his hometown of Detroit, Michigan.
"This movie so (fire)! N for BLACK Friday we supporting This amazing film Queen n Slim. Free movie on me! If u in Detroit FRIDAY enjoy... (sic)! Congrats to @lenawaithe and keep up the incredible work! @queenandslim."
