As hundreds of fans cheered them on, the Harry Potter trio of Daniel Radcliffe, Emma Watson and Rupert Grint walked the red carpet together for what may be the last time ever at the U.S. premiere of Harry Potter and the Deathly Hollows: Part 2 Monday night in New York City.
"It's been the most amazing roller coaster ride," Watson, 21, donning a curve-hugging Bottega Veneta gown, told reporters. Admitting she was feeling "emotional," Watson wore some precautionary waterproof mascara. (At last week's London world premiere, she cried. Her eyes stayed dry on Monday.)
For Radcliffe, also 21, growing up on the Potter movie set "was the most fantastic thing. There are no places more fun for a 12-year-old kid to be than a film set. It's like the ultimate playground. … It's been an exciting, bizarre, wonderful 10 years."
Tom Felton, 23, who plays brooding villain Draco Malfoy, told PEOPLE that being with his fellow wizards at the film's final fete "is very sad. This is the last time we're all going to be together."
Among the stars who helped bid the Quidditch crew adieu at the Lincoln Center screening: Sarah Jessica Parker, Matthew Broderick, Seth Green, Melissa Joan Hart, Marcia Gay Harden and Anthony Edwards.
"I'm still going to stay in touch with everyone," vowed Matthew Lewis, 22, who plays the heroic Neville Longbottom. "We're still really close friends and are friends I'll have for the rest of my life."
