Daniel Radcliffe Was Pranked By 'Harry Potter' Co-Star Alan Rickman With Fart Machine

Daniel Radcliffe and his girlfriend Erin Darke hold hands while enjoying a lunch date at Sushi Samba on Tuesday afternoon (June 16) in New York City.

The 25-year-old English actor’s former Harry Potter co-star Alan Rickman recently chatted about pranking him on set during an appearance on The Tonight Show Starring Jimmy Fallon.

“I knew that Michael Gambon was the owner and user of a remote controlled fart machine… (and in) the third Harry Potter, there was a scene which had 200 kids in sleeping bags. With great grown-up wit I said, ‘We should put the fart machine in Daniel Radcliffe’s sleeping bag’, and we did,” Alan shared.

He added, “The scene… started with me running in saying, ‘Headmaster, what about the children?’ This is how the scene then went: ‘For tonight, let them sleep (fart noise), for in sleep (fart noise), they can fly with the swiftest swallow (fart noise)’.”
