What an absolutely shit film. 
Really.
Yet we watched it all the way through, and I had to really swallow down tears (I will, unchecked, cry at anything including The Simpsons, so this doesn't reflect the quality of the film).
So once she's had the baby and wants to resume her career and he expects her to stay at home and tend house and child and cook his breakfast while he goes out and heroically saves lives... there'll be no friction? Not even a little bit?
Personally I was convinced on first sight that he was Javier Bardem and also that the father's lover was this woman, which she absolutely wasn't. He was rather tasty though, in that way that firemen are (at least in my fantasies).
