Check out the deleted scene below from The Batman. According to Polygon, the clip was unlocked by fans playing the movie's Riddler AR game.
Spoilers for The Batman, but the movie includes a brief scene where the Riddler talks to a mysterious Arkham Asylum inmate in the cell next to his. The character is played by Barry Keoghan and is pretty clearly intended to be this Batman's version of the Joker. You don't get a good look at him in the final film, but the clip below is very different.
The deleted scene features Robert Pattinson’s Batman visiting an inmate at Arkham Asylum, looking for some insight into a criminal mind like the Riddler’s. The dialogue indicates that Batman had his first run-in with the Joker about a year earlier.
Watch for yourself and see how Keoghan stacks up to Heath Ledger, Joaquin Phoenix, Jared Leto, and Jack Nicholson.
