Tom Hiddleston has revealed that he "peed" on Tom Hollander during filming of BBC One drama The Night Manager.
In an interview with Graham Norton, the 36-year-old said: "Tom got stung by a jellyfish and he shouted across the beach, 'I say, old sport, could you come and pee on me?' and I engagingly obliged.
"I've since read up on it and I don't think it works – it's an old wives' tale."
Hiddleston, who was on The Graham Norton Show to promote new film Kong: Skull Island, which he described as "Planet Earth on steroids", also opened up about his time at Eton, and explained that he was given a bizarre nickname.
"Very soon after I arrived I got the nickname 'Piddle' and the boys made up the rhyme, 'Hiddle Piddle did a widdle in the middle of the night'," he said. "My closest friends still call me 'Pid' but it's affectionate now."
Hiddleston was at Eton with actor Eddie Redmayne but, as he admitted to Norton, the pair were not quite in the same league when it came to landing the major parts.
Speaking about the time he and Redmayne were cast in a school production of A Passage to India, Hiddleston said: "I was in A Passage to India with Eddie Redmayne, who played the female lead. I on the other hand, played the front leg of the elephant he rode."
The Graham Norton Show is on BBC One tonight at 10.35pm
