Former House actor Hugh Laurie has said he can't remember any of his lines, but he starts limping "like a dog that's been prodded with electrodes" when they shout "action!".
Talking to Graham Norton on The Graham Norton Show about his famous character, Doctor Gregory House, he said: "I can't remember any of the lines at all but when 'action' is shouted I start limping.
"I'm like a dog that's been prodded with electrodes."
Laurie appears on the show alongside George Clooney, Snoop Dogg, Dwayne "The Rock" Johnson, Jessica Hynes and Britt Robertson.
Fans will be pleased to hear that Laurie isn't permanently living in the USA.
When asked if he's back in the UK for good, he explained: " Yes but I did eventually buy a house in LA.
"The rest of the cast bought straight away but I lived out of a suitcase for a year and a half. Then I dipped my toe in the water and bought a kettle, that was commitment to the country and the first seedling of buying somewhere."
Laurie and Clooney star together in the movie Tomorrowland: A World Beyond.
Both stars did stunt training for the movie, with Laurie revealing: "We trained and got very physical on judo mats.
"I had to throw a punch at George and I was wearing this huge ring that missed him by a skin cell. I could have damaged the most handsome man on the planet."
The Graham Norton Show is on BBC One on 22 May at 10.35pm.
