About a month ago, filmmaker Michael Moore teased that he was working on a “secret project” and name-checked Donald Trump and Roseanne Barr. Tonight on CBS’ The Late Show with Stephen Colbert, the Oscar winner unveiled the title of his movie and offered a few details.

The film will be called Farenheit 11/9, which is, of course, a reference to the day after the 2016 election that saw Donald Trump elected president in what was widely regarded as an upset, at least in the mainstream media. The film will hit theaters on Sept. 21, according to Moore’s website. It will be released by Briarcliff, a new distribution shingle started by Open Road founder Tom Ortenberg.

On May 30 — a day after the Twitter barrage that ended up getting Barr’s revived Roseanne canceled by ABC — Moore posted on Facebook, in part: “Roseanne, the viscous slur at me you retweeted yesterday — if I had the time I’d sue you and drain you of every dime you have. But I’ve got a better idea. As they say in the movies: one down, one to go.”

The post included video from a 1998 episode of Barr’s old talk show The Roseanne Show, one that features her interviewing Moore — she calls him “my blue-collar panelist” — alongside one Donald J. Trump. Moore also said in the post: “I know Roseanne. I know Trump. And they are about to rue the day they ever knew me.”

Moore initially unveiled a film titled Fahrenheit 11/9 last year at the Cannes Film Festival, which was acquired by The Weinstein Company. In the wake of the scandal against Weinstein, TWC was removed from the project and the film was completely re-worked from scratch. Moore retained the original title for the new version.
