But he says it was a little different when he and the rest of the cast shot what would be the final scene from the movie franchise.
Grint says he "was quite surprised how emotional" it was to wrap up shooting on the final movie.
He says once the director said "cut," it "felt like such a final moment." Despite his attachment to the movie and to his character Ron, Grint says the movie is wrapping up when it should. He says the concluding movie - set for next summer - makes it "a good time to finish."
"Harry Potter: Deathly Hallows, Part 1" is the number-one movie at the box office this past weekend.
