Harry Potter Cast Hit New York!

After shedding a few tears at the London premiere, Watson just about held it together in the Big Apple, telling press: "A part of me is very sad and emotional. It's been a tricky juggling act to do my job and be professional but it's very emotional."

Radcliffe also told journalists that he will miss his two co-stars, explaining: "We have a sibling relationship. No one knows what it's been like to go through this mad journey but us."

While Harry Potter may be hanging up his wand for good, Radcliffe has revealed that he hates using public transport because "it can go a bit nuts" when he gets recognised.

Speaking to the Radio Times, Daniel confessed: "I don't take the Tube, because it can go a bit nuts, and if it goes nuts in a small space that can be a bit weird - so I don't know how to use an Oyster card."

He added: "In Harry Potter and the Order of the Phoenix there's a shot of me and Mark Williams going through the gates at a Tube station and I try to put my Oyster card through the machine like it's a ticket, rather than swiping it."
