The story has been bouncing around since The Dark Knight.  Will Christopher Nolan or won’t Christopher Nolan come back for Batman 3?  It’s generally been assumed that that would be the likely scenario, but there’s never been an official announcement.  Just a few days ago, we heard that Nolan was working on the script, which we expected even if he didn’t come back to helm.  Now Empire has an exclusive take where they speak to the man himself and he leaves little doubt:

“It’s becoming inevitable, I’ll put it that way,” says Nolan. “I
feel myself falling into it, I guess. And getting it all figured out
and I’m pretty excited about what we’re doing so… If I haven’t
announced it, I think that people probably all know at this point that
I’m doing it.”

[Empire] Hang on, that’s not 100% clear: so we can safely assume you’re directing?

“I think you can at this point, yes.

I never really thought that he wouldn’t come back, even after Inception waylaid the planet.  The fact that he had parked himself squarely on the Superman franchise as well indicated that he seems to like the thing he has going with the Warners.  And his interest in giving them a definitive Batman trilogy didn’t ever appear to be in jeopardy.  The guy’s a phenomenal talent and it wouldn’t be inconceivable to me that his films end up vying for the signature incarnation of the character down the line.

Thanks to Brian for the tip.
