The actress admitted that she often gets frustrated with her husband Greg Wise because he refuses to open up after fourteen years of marriage.
"There are lots of nice things about British men. For instance, they can be very funny and very self-deprecating," Thompson told the Daily Mail. "In Britain, you very rarely get the sort of macho self-confidence of the Latin man who is so out there and sort of: 'Yes! Of course! I'm lovely!' I like that about them.
"But, on the other hand, when it comes to emotions, they can also be... Well, let's face it, they can be just fantastically retarded, can't they? Almost to the point of lower case autism, really."
Commenting on Wise's attitude, she added: "I've been with him for fourteen years now, and it's sort of like living with a clam. I try and try and try to open the shell, and, yes, after all these years, I have managed to get it very slightly open - and then, sometimes, it shuts again and I have to start all over again. Don't get me wrong, I'm fine with it, and very happily married. But it is the way it is."
Thompson's comments come just weeks after she complained about Wise's reluctance to spend money.
