Liam Neeson says he thought he was drowning in a scene that was shot for his new movie ‘Unknown’.
In an interview with the Boston Herald, the actor talked about one scene in the film where he is pulled unconscious from his car in a river.
He said: “I came to swimming late. I learned to swim at the age of 20.”
On the day of the rescue scene he said he was very nervous: "I've put my head six inches under the heated water and I'm sitting in the back unconscious.
"I’m feeling the water coming up and once it got there, I just panicked. I wasn’t in control.”
In 'Unknown' Neeson's character suffers a near fatal car accident only to discover his identity has been stolen.
“In a nutshell, it’s an edge-of-your-seat thriller, kind of a homage to Alfred Hitchcock of the ’40s, ’50s and ’60s," he said.
The film was shot in Berlin, amid freezing temperatures: “It was the coldest January and February in 20 years. Treacherously cold.
“There was frost on the ground and ice, and we had a lot of physical activity outside. There was a challenge just to execute the film in that.”
Speaking about working on tough physical scenes, the 58-year-old actor said: "I don't do my own stunts. I do my own fighting, [he's an ex-boxer] which I don't regard as a stunt.
"My dear friend and stunt double has been doing the heavy stuff for about 12 years now.”
He added: “I’ve gotten a new lease of life with this ‘Taken’ movie at the age of 58. Did I say 58? 37!
“It’s great to play an action hero.”
'Unknown' is released in Irish cinemas on 4 March 2011.
