This Changes Everything is a 2018 American documentary film, directed by Tom Donahue. An examination of sexism in the Hollywood film industry, the film interviews a variety of actresses and women filmmakers on their experiences in the industry.

Featured in the movie is "film director Maria Giese, who was a key instigator of the ACLU and federal investigations, has been a feminist activist in Hollywood since 2014, when she wrote an explosive article for Ms. magazine in which she observed that entertainment is the worst offender of Title VII employment anti-discrimination laws of any U.S. industry. She casts a somewhat jaundiced eye on enterprises like Time’s Up, which was created within the Hollywood establishment to address workplace sexual harassment and assault, observing that it’s one of several collegial, inside-industry efforts undertaken to avoid legal action and government oversight. Those threats have served as a sort of twin sword of Damocles, forcing studios, networks and agencies to do the right thing after decades of denying there was a problem".
