The 62-year-old Italian has joined the film's cast, with recruitment still afoot, and it appears that the DC Comics character will be key to the plot, albeit still unknown.
Turturro's involvement was announced by the movie's director and writer Matt Reeves, who posted as much to Twitter on Friday, using a GIF from the actor's iconic performance in 1998's The Big Lebowski.
Carmine Falcone is a crime boss who is an enemy of Batman in the comics but a friend of Bruce Wayne's. The character is played by John Doman in FOX TV series Gotham, in which he is portrayed as Gotham's first big underboss. Before that, he was played by Tom Wilkinson in Christopher Nolan's Batman Begins.
It is rumored that Reeves will be drawing from the comics run The Long Halloween, in which Carmine's father brings his son to Thomas Wayne's mansion to be stitched up after he gets shot. Thomas agrees and a young Bruce watches on as Carmine is made whole again. That bit makes it so that the Wayne family develops a relationship with their patient.
Providing that's the angle Reeves is going with, we can expect Thomas Wayne to be in the movie too.
So far, we know that Batman is being played by Robert Pattinson. Zoe Kravitz will be taking on the form of Catwoman while Paul Dano will be the Riddler.
Detective James Gordon will be played by Jeffrey Wright and Andy Serkis has landed the role of Alfred Pennyworth.
The Batman is due to hit cinemas in June of 2021, with filming to begin in London's Leavesden Studios in the first quarter of 2020.
