'Joker' Movie: Alec Baldwin to Play Bruce Wayne's Father

Robert De Niro, Zazie Beetz and Marc Maron are already on the call sheet.

Alec Baldwin is joining Joaquin Phoenix in Joker, Warner Bros.' stand-alone movie centered on DC’s clown prince of crime.

Baldwin is the latest high-profile actor to join the project, which is scheduled to begin shooting in two weeks. Robert De Niro, Deadpool 2 breakout Zazie Beetz and Glow actor Marc Maron are already on the call sheet.

Phoenix is set to portray the DC Comics villain in a film that is more moderately budgeted and darker than the studio’s other DC-based movies that make up its shared universe. The project is also described as more of a dark character study than a crime thriller, with Taxi Driver and The King of Comedy as the tonal watchwords.

Baldwin has been tapped for the role of Thomas Wayne, who in Batman lore is the father of Bruce Wayne, the future caped crusader.

But this being a movie project that will veer off-center from the traditional Batman canon, sources say the script paints Thomas Wayne as a cheesy and tanned businessman who is more in the mold of a 1980s Donald Trump.

Baldwin already has plenty of experience playing Trump via Saturday Night Live, which recently earned him a second Emmy nomination for the role. The actor currently can be seen onscreen in the Paramount hit Mission: Impossible — Fallout, and recently wrapped a role in Motherless Brooklyn, a crime drama being made by Warners.
