David Fincher's upcoming Herman J Mankiewicz biopic, Mank set for release on Netflix on December 4. 

The black-and-white film, featuring Oscar-winner Gary Oldman in the title role, will head to the digital platform a month after it starts playing in select theatres.

The film centres around Mankiewicz, the screenwriter of Orson Welles' Citizen Kane, and his battles with the film's director and star Orson Welles over screenplay credit for the 1941 cinematic masterpiece. Mank is based on the script by Fincher's father, Jack Fincher, who had written the draft before his death in 2003.

The Souvenir star Tom Burke plays Welles, with Amanda Seyfried starring as yesteryear actor Marion Davis, Lily Collins as Mankiewicz's secretary Rita Alexander and Tuppence Middleton as Sara Mankiewicz.

Considered to be one of the best films of all time, Citizen Kane managed to win just one Academy Award, which was for the best original screenplay.

This will be Fincher's first feature release since 2014's Gone Girl. Fincher backs the film alongside producing partner Cean Chaffin and Douglas Urbanski.
