Principal photography has begun on Warner Bros. Pictures’ “Joker,” starring Oscar nominee Joaquin Phoenix in the title role, alongside Oscar winner Robert De Niro, and directed, produced and co-written by Oscar nominee Todd Phillips.

“Joker” centers around the iconic arch nemesis and is an original, standalone story not seen before on the big screen.  Phillips’ exploration of Arthur Fleck (Phoenix), a man disregarded by society, is not only a gritty character study, but also a broader cautionary tale.

The film also stars Zazie Beetz (“Deadpool 2”), Bill Camp (“Red Sparrow,” “Molly’s Game”), Frances Conroy (TV’s “American Horror Story,” Hulu’s “Castle Rock”), Brett Cullen (“42,” Netflix’s “Narcos”), Glenn Fleshler (TV’s “Billions,” “Barry”), Douglas Hodge (“Red Sparrow,” TV’s “Penny Dreadful”), Marc Maron (TV’s “Maron,” “GLOW”), Josh Pais (upcoming “Motherless Brooklyn,” “Going in Style”), and Shea Whigham (upcoming “First Man,” “Kong: Skull Island”).

Phillips (“The Hangover” trilogy) directs from a screenplay he co-wrote with writer Scott Silver (“The Fighter”), based on characters from DC. The film is being produced by Phillips and Bradley Cooper under their Joint Effort banner, and Emma Tillinger Koskoff.   It is executive produced by Richard Baratta, Joseph Garner and Bruce Berman.

Behind the scenes, Phillips is joined by director of photography Lawrence Sher (upcoming “Godzilla: King of the Monsters,” “The Hangover” trilogy), production designer Mark Friedberg (“Selma,” “The Amazing Spider-Man 2”), editor Jeff Groth (“War Dogs,” “The Hangover Part III”), and Oscar-winning costume designer Mark Bridges (“Phantom Thread,” “The Artist”).

A Warner Bros. Pictures presentation, in Association with Village Roadshow Pictures, in Association with BRON Creative, a Joint Effort Production, “Joker” is set for release October 4, 2019, and will be distributed worldwide by Warner Bros. Pictures.
