No joke, Alec Baldwin has dropped out of the "Joker" movie that he reportedly only joined a few days ago.

On Monday, Deadline reported that Baldwin was set to play Thomas Wayne, Batman's dad, in director Todd Phillips's film opposite Joaquin Phoenix as the titular villain. The cast includes Robert De Niro, Frances Conroy, Marc Maron, and Zazie Beetz.

But Baldwin himself threw cold water on the casting report earlier today on Twitter:

USA Today confirmed with the actor that he dropped out due to scheduling conflicts.

"I'm no longer doing that movie," he said. "I'm sure there are 25 guys who can play that part."

Production begins on Sept. 10, so Phillips had better find a replacement soon. Not much is known about the movie, other than that it is a "gritty character study." But Baldwin's tweet seems to confirm rumors that Thomas Wayne will be portrayed as a "cheesy and tanned businessman who is more in the mold of a 1980s Donald Trump."
