Ray Winstone didn't hold back as he revealed what he really thinks of Jack Nicholson as he branded the Hollywood star 'rude' and 'up his own a*'.
The Quadrophenia star, 68, reignited his 20-year feud with the American A-lister after the pair worked together on the Oscar-winning film The Departed back in 2006.
While the pair were known to have clashed at the time, almost two decades later it appeared Ray's opinion of the now 88-year-old still hasn't changed.
Speaking on Eamonn Holmes and Paul Coyte's podcast Things We Like with Eamonn & Paul, the Irish presenter straight up asked him whether he liked Jack.
Confirming the pair struggled to see eye to eye he confirmed: 'No. We just didn't get on. I just found him... Listen, he's getting older, and maybe there are a lot of things going on with him.
'I didn't like him, I thought he was so far up his own a--e it was unbelievable. And he was very rude.
'He was very rude to me, he was rude to my wife, if he had been a younger man, I'd have definitely knocked him out.'
Giving credit to Jack's talent in the industry he added: 'But you've got to give him because he's an older man, much older than me.
'He's fantastic at what he does, brilliant at what he does. He's a great writer as well, by all accounts, at least that's what he kept telling us.'
'But at the same time, I can't make an excuse for him. My grandfather was an old man, but he was a gentleman. He was a lovely man.'
'So fk him, basically. Really. Why should I say I like him? I don’t. You ask me the question, you get the answer.'
Ray starred as Arnold 'Frenchie' French, the murderous enforcer to Jack Nicholson's mob boss in the Oscar-winning film directed by Martin Scorsese.
The star has spoken about his feud with Jack in the past after he admitted they 'didn't click'.
Speaking at a BAFTA Life In Pictures event in 2014 he confessed: 'Me and Jack did not seem to get on too well. Maybe he was going through a funny time.

'Everyone else loves him to death - I just wanted him to be a great guy. We just did not click.'
Later in an interview with The Independent, Ray admitted he had no idea why Jack didn't like him but confessed: 'It doesn't worry me. It doesn't shock me. You clash a little bit. He's not the first person I've clashed with. He won't be the last.'
He added: 'I don't like arrogance. There's no need for it. This kind of feeling of being above everyone else. We all end up in the same hole in the ground.'
'But some people have this smarmy little side mouth.... And there are different ways of dealing with that. You either say your piece and tell them to shut the fk up. Or you punch them in the mouth.'
Yet despite not connecting with him on a personal level, Ray insisted it wouldn't stop him working with Jack in the future as he added: 'Of course I want to work with him again! He's a fantastic actor.'
Elsewhere in the interview, Eamonn also didn't hold back as he let rip on his former colleagues in the TV industry as he branded them 'false'.
As Ray spoke about his time living in Los Angeles and how the artificial buzz of Hollywood ultimately drove him back to the UK, Eamonn jumped in to express his dislike for the fake relationships he has found in the entertainment industry.
The presenter said in a mocking tone: '''I don't like this character, I don't like so and so, I like that person, I didn't get on with them''.'
He went on: 'That's what the business is based on. I mean, I'm like you [Ray]. I get myself into trouble because if I don't like someone, they'll know I don't like them.'
'And there are so many horrible people that you end up with. People say: ''Oh, he's lovely, he's fantastic'',' he added.
