Affleck portrayed the caped crusader in this year's "Batman v Superman: Dawn of Justice" and had been rumored to be the studio's top choice to helm the film. Tsujihara confirmed they were moving forward with him in the director's seat Tuesday at CinemaCon, an annual gathering of theater owners in Las Vegas.
The standalone Batman feature is part of Warner Bros. plans for an expanded DC Comics cinematic universe, similar to that of the Disney and Marvel collaboration. Warner Bros. has at least 10 features in the works, including "Suicide Squad," ''Wonder Woman" and "Justice League." Unsurprisingly, those films comprised a major portion of Warner Bros.' presentation, signaling that the studio is moving forward energetically with its original plans despite reports that perhaps "Batman v Superman" is not performing as well at the box office as the studio would have liked.
Affleck, who is also directing "Live By Night" for the studio, made an appearance with Amy Adams, who plays Lois Lane. He confirmed that both would be joining Zack Snyder's "Justice League," which is currently in production in London.
"Suicide Squad" director David Ayer and stars Will Smith and Margot Robbie were on hand as well to hype the supervillains gone straight pic, which launches on August 5 with intense footage focusing heavily on Robbie's Harley Quinn.
Warner Bros. also trotted out stars and footage from a number of their upcoming films including the Harry Potter spinoff "Fantastic Beasts and Where to Find Them," ''The Lego Batman Movie," the Russell Crowe and Ryan Gosling comedy "The Nice Guys," and the Emilia Clarke romantic drama "Me Before You."
But beyond the individual films, a big focus was the studio's ongoing commitment to its filmmakers and the specialness of theatrical presentation.
The threat of The Screening Room, a proposed at-home viewing experience of first-run movies, has loomed large over the annual conference where theater owners come not just to check out the new studio slates and mingle with stars, but to see the latest technologies that promise to enhance the theatrical experience for audiences. Major filmmakers like Steven Spielberg and Peter Jackson have come out in support of the service, but the industry on the whole remains divided.
"I assure you we are not going to let a third party or middle man come between us," Tsujihara told the audience of exhibitors. "When there are new technologies ... we will explore them with each of you. We know the status quo is not an option."
Not every studio has taken a hard stand. On Monday, "Star Wars: The Force Awakens" director J.J. Abrams - a Screening Room backer - urged the conference to be open-minded about innovations.
"Hangover" director Todd Phillips on Tuesday, however, came out strongly against the idea of the Screening Room without mentioning it directly while promoting his new Jonah Hill and Miles Teller comedy "War Dogs."
"Why are we in such a rush to turn movies into television? It doesn't make sense to me. Movies are special," Phillips said. "We need to do everything we can to protect that part of the experience."
