Reeves said there will be a "rogues gallery" during an interview with The Hollywood Reporter earlier this year, while spilling more details about the highly-anticipated superhero flick.
"It's very much a point-of-view-driven, noir Batman tale," Reeves said at the time. "It's told very squarely on his shoulders, and I hope it's going to be a story that will be thrilling but also emotional. It's more Batman in his detective mode than we've seen in the films."
Turturro's credits include "The Big Lebowski," "Monk" and the "Transformers" series. He can be seen next in "The Big Lebowski" spinoff "Jesus Rolls" and HBO's "The Plot Against America"
