Los Angeles - Liam Neeson quit drinking last year.
The 61-year-old actor has revealed he made the conscious decision to ditch alcohol after he realised he had been boozing "too much" since the death of his wife Natasha Richardson, following a skiing accident in Montreal, Canada in March 2009.
The Non-Stop star told the April issue of GQ magazine: "I was drinking too much. It started since my wife died.
"Never at work, never would do it like that, but this time of night? Sitting with you, I'd easily have - I'd be on my second bottle. Before we finished, I would have been halfway down a third."
The Northern Irish actor also claimed he was filming a sex scene for Woody Allen's movie Husbands and Wives in 1992 when the director's affair with his then-girlfriend Mia Farrow's adopted daughter first broke.
He said: "There was one incident - people think I've made this up, but no. There's a scene where I'm performing a sex acton Judy Davis, right. Judy and I are in bed - obviously covered up (...) the crew are all ready, and we're waiting for Woody. No-show. It's starting to get a bit uncomfortable.
"Anyway, he came out after about 20 minutes (...) there was no apology, nothing. What happened, his lawyer had gotten in touch with him to say Ms Farrow has found naked photographs of her adopted daughter."
The Taken 2 star formed a close friendship with Mia in the 90s and recalled meeting up with her and Natasha in Ireland a few months later.
He said: "We had a couple of Guinnesses one night, and I told Farrow I was going to marry this woman."
