Here’s the interview in full (Warning: Spoilers):
Movie-Rumors (MR): So, Christopher, we take it Robin has an important part to play in The Dark Knight Rises?
Christopher Nolan (CN): I don’t want to give too many details away at this point.
MR: So you don’t deny it!
CN: Deny what?
MR: When Robin joins Batman in fisticuffs with the baddies, do we get “Kapow” splashed across screen?
CN: I think you’ve misunderstood.
MR: Have you gone for a darker, grounded in reality Boy Wonder Robin?
CN: I didn’t say Robin was in this film.
MR: Do you anticipate a spin-off from this movie focusing more on Robin?
CN: Robin hasn’t invaded my consciousness to the degree that he’s invaded yours.
MR: Does Catwoman fall in love with Robin?
MR: If not, say no. If yes, say nothing.
MR: That’s what we thought!
