On Monday, news broke that the actor was in talks to play Thomas Wayne in Todd Phillips' Joker stand-alone movie.

In comic book lore, Thomas Wayne is a physician, philanthropist and father to Bruce Wayne (the future Batman). Sources on Monday told The Hollywood Reporter that in a departure from the comics, the Joker script called for Thomas Wayne to be a cheesy and tanned businessman who is more in the mold of a 1980s Donald Trump.

Baldwin is citing "scheduling issues" as his reason for dropping out. But he also addressed the new take on Wayne.

The actor, who recently earned a second Emmy nomination for playing Trump on Saturday Night Live, tweeted Wednesday that he had not "been hired to play a role in Todd Phillips’ JOKER as some Donald Trump manque. That is not happening."

Phoenix is playing the Joker, while other stars include Robert De Niro, Deadpool 2 breakout Zazie Beetz and GLOW actor Marc Maron. The film is set to begin shooting in two weeks.

Warner Bros. has slated Joker to open Oct. 4, 2019.
