The British actor used the actress, who has starred in The Bounty Hunter and The Switch, as an example as someone who doesn't have a good movie career but still maintains A-list celebrity status.
He said: "If you look and analyse the careers of many, many stars, you'll find that they're mostly sustained by the business. You'll find there's lots of women and lots of men in the business that the powers that be decide are right for their business, and they'll stand with them for quite a long time.
"OK, something will go wrong, like Jennifer Aniston will have one too many total flops, but she's still a member of that club. And she will still manage to – like a star forming in the universe – a whole lot of things will swirl around her and it will suddenly solidify into another vital tasteless romcom, a little glitter next to the Crab Nebula."
The outspoken My Best Friend's Wedding actor also gave his opinion on fellow British actor Colin Firth, calling his performance in musical Mamma Mia! "careericide".
He told BBC Radio 4: "Colin Firth I don't think was at all good in Mamma Mia! I would have thought it was almost a careericide. On the other hand, I think his performance in A Single Man was the best performance of his life."
