Heart Radio interviewed the trio last month as they went about promoting Harry Potter and the Half-Blood Prince.

Of particular interest was Dan's scoop that "there is a Quidditch element to one of the rides." He also talks about Nagini's role in Harry Potter and the Deathly Hallows.

In the interview, Emma admits she would choose Ron over Harry, and Rupert talks more about his ice cream van and Swine flu.
