"When I made the decision to make the son21,"says Cohen, "I got a very angry phone call from [Weisz's]agent, saying she'll never play the mother of a 21-year-old. I said, "Okay, good, fine, bye." It was critical to me to have this old-bull/young-bull family element. The father can't yet recognize the son's manhood, so it was important for the kid to not be a baby." (According to Weisz's reps, the actress never read the script and didn't consider doing the film because it would require a five-month trip to China with her infant child.)
