Stephen Graham has revealed he had emergency surgery on a plane going from the UK to the US.
The Adolescence star, 51, had to get a surgical catheter put in after urinating blood several hours into one of his latest flights.
During an appearance on Late Night with Seth Meyers, Graham explained that he initially couldn’t urinate, saying: "I'm like, ‘Oh, this doesn't feel right.’
“I knew I had to, and then silly Stephen thought, 'Oh, well, if I go back to my seat and I just keep drinking water, at some point it will happen.'"
When he went to the toilet an hour later, he said, "long story short, all of a sudden I went, but it was just pure blood."
The Thousand Blows star explained: “I couldn't stop this trajectory of blood and I'm having a slight panic attack. I'm about to cry and I'm having a moment.”

Graham then remembered there was a doctor on board - a man he’d taken a selfie with on the bus coming onto the plane, who’d explained he was a medic.
Recalling the “very scary” experience, the actor reached out to the doctor on the plane for advice and help.
"Next minute, the doctor comes around the corner, and he goes, ‘Stephen!’ and I'm like 'Doc, hello!', and I explained the situation,” he said.
"He had another friend with him, who was a surgeon, so I'm there, and I explain. He's like, okay and the surgeon, Dr Haji, says, we can work this out."
They sterilised the lounge area between the economy and first class sections and brought out a catheter from an emergency medical box.
Graham - whose Netflix drama Adolescence has been breaking ratings records - explained that the crew kept the curtains drawn so he could have privacy during the operation.
"I drop me kecks, I get on the couch, and he performs a catheter operation there and then,” Graham recalled.
"The relief was unbelievable as you can imagine. It was a little clot that had got stuck behind, well, not little, but, had got stuck behind my urethra.
"I went to the toilet, and it was one of the nicest experience with me and my penis!"
The actor joked that he "he came running out like a kid that had just learned to use the toilet".
