WATCH: Leonardo DiCaprio thanks fellow The Revenant cast member 'Dumble Gleeson' in SAG Awards speech
Yet another Irish name has left a Hollywood star tongue-tied on stage at an awards ceremony.
Leonardo DiCaprio struggled to pronounce Domhnall Gleeson during his SAG Awards acceptance speech on Saturday night.
Unfortunately he referred to the Dublin actor and his The Revenant co-star as 'Dumble'.
DiCaprio bagged the Best Actor award for his performance in director Alejandro González Iñárritu's masterpiece.
It was quite a moving speech in which DiCaprio thanked his fellow actors and encouraged young actors to watch the history of cinema because "when the history of cinema unfolds you realise we all stand on the shoulder of giants."
He heartfelt speech also involved thanks for the director and cast of The Revenant.
"This film would not have been possible without the craft of our director, Alejandro González Iñárritu. Alejandro, thank you for your fierce authenticity, your creative genius, a genuis you share with our cinematographer," he said.
He continued, "Our entire crew, the entire cast I got to work alongside - Domhnall Gleeson, Will Poulter, Forrest Goodluck, Arthur RedCloud, Duane Howard and of course the great Tom Hardy."
Unfortunately his pronunciation of 'Domhnall' sounded more like a wizard from Harry Potter...
Leo is not the first to fall foul of a tongue-twister of an Irish name, with all their vowels and strangeness.
Saoirse Ronan has had more than her fair share of trouble in Tinseltown. The most hilarious example was Dennis Quaid's attempt at pronouncing her name during the Golden Globes nominations announcement.
Quaid (61) was naming the nominees in the Best Actress - Drama category when he hit the Saoirse wall and ended up announcing 'Sheesha' Ronan, whoever she is, as one of the nominees.
His gaffe didn't get past Twitter, of course, where he was lambasted for 'butchering' the Irish actress's name.
