As children, Grint and his co-stars Daniel Radcliffe and Emma Watson had their lives transformed by their wizarding roles in the big-screen adaptation of JK Rowling's books between 2001 and 2011.
Grint was 11 when he was cast as Ron - who is characterised as one of Harry Potter's best friends at Hogwarts - and now describes the experience as being "crazy".
"It changed my whole life quite quickly," he said. "I was a huge fan of the books, so for me it was like stepping into the books, and that was very special."
