Los Angeles - Daniel Radcliffe has done a "fair share of crying" about Harry Potter.
The British actor - who has portrayed the boy wizard in the adaptations of JK Rowling's novels for the last decade - admits he isn't particularly sad about leaving the movie franchise, but found the last film poignant just because of the story.
He said: "What I was impressed by was that it wasn't a sense of nostalgia and emotion caused by my own personal relationship with the films, I was a wreck because of the film itself.
Heartbreaking
"You've got to have a heart of stone to not find part of it - especially Alan Rickman's performance - heartbreaking, so yeah, I've done my fair share of crying already."
However, the 21-year-old actor believes the series of movies - also starring Emma Watson and Rupert Grint - has proved franchises can grow rather than diminish as time continues.
He told MTV News: "It doesn't have to be a law of diminishing returns after the first film comes out.
"Providing a script is good enough. I would absolutely do another franchise, but it's not something I'm looking for in the next couple of years, certainly."
