"It was actually okay," Grint, 22, said of his onscreen kiss with Watson in Harry Potter and the Deathly Hallows, which opened in theaters Friday. "It was just the anticipation. Neither of us were looking forward to it."
Grint does, however, acknowledge that may seem a bit unbelievable to most fans.
"It sounds crazy, Emma's amazing," he says. "I've seen her grow up and known her since she was nine. It just doesn't feel right."
What does feel right is leaving the Potter franchise behind.
"In terms of filming, yes, it really does feel over now," he said, adding, "There's a real sense of freedom now. It's a good time to finish, I think. As much as I'm going to miss it I'm ready to move on and do different things."
In the meantime, Grint has an answer for anyone who questions whether or not children can handle some of the scarier parts of the next two films.
"Kids like to be scared … so they won't be too troubled," he says. "Naturally these films are getting darker as we are growing up and the environment changes. We see a much harsher side of all the character, of being on the run, missing their families and being tired… and living in this little tent together causes clashes."
