Part of the screen test, Pattinson revealed during The Batman’s portion of DC FanDome, involving putting on the actual Batsuit and shooting a couple scenes.
For example, Matt Reeves wanted Robert Pattinson to play his young “recluse rockstar” version of Bruce Wayne in The Batman.
As Reeves and Pattinson joked about the experience, they both recalled just how sweaty Pattinson got inside the Kilmer Batsuit.
When a big studio is casting one of their flagship characters, it’s customary to do some kind of screen test.
