Speaking exclusively with Screen Rant while doing the press junket for Thor: Love and Thunder, Bale addresses this question. According to the actor, no one has apparently brought up the idea of him reprising his DC role. Even if there have been offers, he makes it clear that the only reason he would revisit Batman is if Nolan asks him. Read Bale's answers below:share
No. No one's ever mentioned it to me. No one's brought it up. [...] Occasionally people say to me, "Oh, I hear you were approached and offered all this." And I'm like, "That's news to me. No one's ever said that."
I had a pact with Chris Nolan. We said, "Hey, look. Let's make three films, if we're lucky enough to get to do that. And then let's walk away. Let's not linger too long." In my mind, it would be something if Chris Nolan ever said to himself, "You know what, I've got another story to tell." And if he wished to tell that story with me, I'd be in.
