We are so sorry to inform you that the NYC Harry Potter Event has been cancelled. The police changed their minds on how many people can be at the SCREAM AwardsI did assume that everything would have been cancelled, but there are photos of Daniel on stage with Samuel L. Jackson, via their Twitter (see below, and if you have photos, feel free to send them in)
Update: There is now a video of Daniel accepting the Ultimate Scream (Harry Potter and the Deathly Hallows part 2) and Best Fantasy Actor (himself) awards from Samuel L. Jackson.
Update: 18th October 2011. A video from a chat between Samuel L. Jackson and Dan via mikethe fanboy.com
