Harry Potter films get all-night screening at BFI Imax
London's BFI Imax is to hold all-night screenings of the Harry Potter series to mark the release of the final instalment.
The seven already released films will be split over two nights for the 20-hour marathon all-nighters on 17/18 and 24/25 June.
Fans are also invited to dress up in wizarding costumes for the occasion.
The final film in the series, Harry Potter and the Deathly Hallows - Part 2, opens in cinemas on 15 July.
"We can't wait to welcome the biggest and bravest Harry Potter fans in the country," said Justin Johnson, head of operations at BFI Imax.
"If they see every film they'll spend almost 20 hours in the company of all their favourite characters!
The BFI said it would be giving fans free tea and coffee during 30-minute breaks in between films to help everyone stay awake through the night.
