Mank is a 2020 American black-and-white biographical drama film about screenwriter Herman J. Mankiewicz and his development of the screenplay for Citizen Kane (1941). It was directed by David Fincher based on a screenplay by his late father Jack Fincher, and was produced by Ceán Chaffin, Douglas Urbanski, and Eric Roth. It stars Gary Oldman in the title role, alongside Amanda Seyfried, Lily Collins, Arliss Howard, Tom Pelphrey, Sam Troughton, Ferdinand Kingsley, Tuppence Middleton, Tom Burke, Joseph Cross, Jamie McShane, Toby Leonard Moore, Monika Gossman, and Charles Dance.
Jack Fincher wrote the script in the 1990s, and David originally intended to film it after he completed The Game (1997), with Kevin Spacey and Jodie Foster as the leads. It never came to fruition, and Jack Fincher died in 2003. Eventually, the project was officially announced in July 2019, and filming took place around Los Angeles from November 2019 to February 2020. To pay homage to the films of the 1930s, Mank was shot in black-and-white using RED cameras.
Mank had a limited theatrical release on November 13, 2020, and began streaming on Netflix on December 4. The film received positive reviews from critics, who praised Fincher's direction, as well as the acting (particularly Oldman and Seyfried), cinematography, production values, and musical score. The film earned a leading ten nominations at the 93rd Academy Awards, including Best Picture, Best Director, Best Actor (Oldman), and Best Supporting Actress (Seyfried), and won for Best Production Design and Best Cinematography. It also received a leading six nominations at the 78th Golden Globe Awards, including Best Motion Picture – Drama.
