James Nesbitt has spilled the beans on what really happened after a heavy drinking session with Liam Neeson in which the Taken actor inadvertently wet himself.

The pair were filming their movie Five Minutes of Heaven in Northern Ireland back in 2008.

But after a heavy day out in Belfast, Liam was photographed sporting a mysterious wet patch between his legs — which ended up in the papers with a headline ‘Schindler’s P****d’, a play on his Oscar-winning movie Schindler’s List.

Jimmy (59) revealed: “I did a film years ago with Liam for the first time. And on the first night, Liam said, after the read-through: ‘Will we go and have a wee drink somewhere?’ Because he hadn’t been back in Belfast for a long time.

“So I phoned up a guy, Niall [McKenna] from James Street South restaurant, and said: ‘Look, any chance Liam and I can come in and have a bit of wine and cheese or whatever?’

“He said: ‘Lunch is finished. Come on in and I’ll put you in the corner while we’re getting ready for the evening.’

“So we went in. Five hours later, six bottles of red wine later, Niall came up and he said: ‘Right, you boys better get out, because you’re full and the evening guests are about to arrive at the restaurant.’”

Things took a turn for the worst at this point, with Liam getting caught short after the marathon wine quaffing.

He continued: “We go to leave and Liam says: ‘I just need to use the toilet.’

“I’m sat on a wee bench in James Street South and the people are coming in going: ‘Ach, Jimmy, how are you doing?’

“All of a sudden, the toilet doors — there were, like, swing saloon doors — flung open and Liam came running out.

“And Liam is only dressed exclusively by Armani. He’s a big, big man and he was wearing this light blue suit.

“He came out — and he obviously hadn’t made it in time. He’d p****d himself.

“And he’s standing there and I went: ‘For f**k’s sake, Liam.’

“He said: ‘I didnae make ’er in time.’”

Jimmy told The Whiskey N White podcast how the pair tried to get back to a hotel unscathed — only to get snapped by star-spotting punters out on the town.

He said, laughing: “I said: ‘Right, come on, you. Let’s get out of here!’

“So we leave and we’re walking through the streets. It was a beautiful spring evening in April.

“He said: ‘Come on, let’s go to your hotel.’ I was staying at Ten Square.

“I said: ‘We can’t go to the hotel — look at the state of ye.’

“He said: ‘Ah, it’ll be fine.’

“We’re walking and I see these young lads approach, sort of student guys.

“I thought: ‘Aw, f**k.’ One went, ‘Jimmy Nesbitt,’ and the other went, ‘Liam f**king Neeson. Can we have a photo?’

“And I said: ‘No, boys, don’t take a photo.’ But Liam said: ‘I’m back home. I’ll take a photo.’

“So they take a photo. Next week, Liam was filming his part. I was away in Moscow to watch [Manchester] United play Chelsea.

“And a couple of days later there it is in the paper, with the headline ‘Schindler’s P****d (himself)’.”
