Daniel Radcliffe began his U.S. promotion of this Halloween's release of Horns in New York on Monday, when he attended the New York City premiere at the Landmark's Sunshine Cinema. Photos of Dan with costars Juno Temple and Heather Graham, as well as the filmmakers, at The Cinema Society New York-hosted screening can be found here.











Dan also promoted Horns on The Tonight Show Starring Jimmy Fallon, which will air Tuesday night on NBC, where he spoke about the now-famous 'Daniel Radcliffe/Daniel Boringcliffe' meme, and even performed the 'Alphabet Aerobics' rap by Blackalicious. Photo previews of the Harry Potter actor with Fallon can be seen below.
