It has long been rumored that Liam Neeson returned to film a scene for Christopher Nolan’s The Dark Knight Rises, but now Neeson commented on it himself.

“I can tell you nothing about Dark Knight Rises, seriously,” Neeson told ShowbizSpy. “I was on set for maybe an hour-and-a-half and the director didn’t tell me anything of what it’s about. So, I’m being very honest when I say I have no idea what’s going to happen.”

Neeson played villain Ra’s al Ghul in Nolan’s Batman Begins, which hit theaters in 2005. We’ll have to wait and see on July 20 if he actually filmed a scene.

The highly-anticipated film stars Christian Bale, Michael Caine, Gary Oldman, Morgan Freeman, Tom Hardy, Anne Hathaway, Joseph Gordon-Levitt, Marion Cotillard, Juno Temple, Josh Pence, Daniel Sunjata, Nestor Carbonell, Matthew Modine, Tom Conti, Joey King, Brett Cullen, Chris Ellis, Josh Stewart, Christopher Judge, Adam Rodriguez and Rob Brown.
