The 58-year-old actor – whose wife Natasha Richardson died in a skiing accident in Canada in March 2009 – revealed starring with Diane Kruger, 34, and January Jones, 33, on thriller ‘Unknown’ made the tough filming conditions a little easier to bear.
When asked how he found working with the pair, Liam told British website AskMen: “It’s very easy on the eyes to see them first thing when you get to the set at 6 am, if I may say so.”
Liam recently revealed his grief at the death of Natasha – with whom he has two sons Michael and Daniel – affects him most in "the middle of the night".
He said: "It's easy enough to plan jobs, to plan a lot of works. That's effective. But that's the weird thing about grief. You can't prepare for it. You think you're gonna cry and get it over with. You make those plans, but they never work.
"It hits you in the middle of the night - well, it hits me in the middle of the night. I'm out walking. I'm feeling quite content, and it's like suddenly, boom. It's like you've just done that in your chest."
