The 47-year-old actor, who tied knot with Daniel Craig in 2011, said it was never an 'ambition' of hers to marry until she met Craig.
"I don't think mine's particularly exceptional apart from that we're both in the public eye. But I never thought I would get married. It was not an ambition of mine. It was the opposite," Weisz told ES magazine.
"I couldn't relate to romantic comedies - marriage seems to be the whole point of them. Then it just happened, happily, at a more mature moment," she added.
