The 'Star Wars: The Force Awakens' actor was on the phone to Ryan Tubridy on Ireland's RTE Radio One as he took a taxi to the airport in London but the chat was interrupted by Domhnall suddenly saying "Whoa".
When questioned by the host if he was ok, Domhnall replied: "There was just a crash. We're not speeding, we're going at a reasonable rate.
“I don't want to get the driver in trouble, he's an excellent driver! We're going to the airport."
However, ever the professional, Domhnall managed to continue the interview and even joked about how awkward it was to accept an award for his father Brendan Gleeson at the British Independent Film Awards because Domhnall had also been nominated.
He said: "I was nominated against my father and I lost to him, my dad was not there so I had to go up and accept the award.
"Alicia Vikander was the lady handing out the trophy and she was standing there in horror because she thought that I had heard the wrong name and was strutting up because I thought that I had won.
"That was one of the more awkward experiences of my life."
