Matt Damon argues with his wife over 'Downton Abbey'.
'The Monuments Men' actor admits he's a big fan of the ITV period drama and fell out with his wife Luciana Barrosa after she watched a run of episodes without him.
Speaking on 'The Graham Norton Show', which airs tonight, Damon said: "My wife is an addict. It's a problem.
"We were supposed to watch it together and I came to bed one night and she said, 'I've just watched six of them - I'll tell you what happened!'
"She wanted to watch the seventh and didn't want to go back to the beginning. So she's done the whole thing and I am on my own."
The 43-year-old star, who has three daughters with wife Luciana, along with her daughter from a previous marriage, has been married since 2005 and is currently missing his family while promoting his new film 'The Monuments Men', co-starring George Clooney, who has also said he's a fan of 'Downton Abbey'.
But he appeared to be enjoying himself on Graham's sofa, declaring: "This is the best time I have ever had on a chat show."
Meanwhile, Damon has said he would love to appear in 'Downtown Abbey' with co-star Hugh Bonneville, who plays Robert, Earl of Grantham.
Asked if Bonneville had convinced him to guest-star on the show yet, he said: "He could, he could.
"Everybody loves that show. My wife loves the show more than anybody. I don't know [if she loves it more than Michelle Obama].
"They would have a lot to talk about."
