'Nine Months' is another typical romantic comedy. It has its funny moments. It has its unfunny moments (especially the toilet humour). While, in my opinion, the film could have been a great comedy, some of the humour is just flat and forced into the screenplay. Generally speaking, it's not a bad film.
Chris Columbus's direction isn't exactly bad as he does manage to make 'Nine Months' a feel-good film. Hugh Grant doesn't seem like the ideal choice for the role. I just didn't find him convincing enough, even though he's known for his rom-com movies. Julianne Moore is a delight to watch even though her role is less comedic and challenging. Joan Cusack is hilarious. Tom Arnold is quite annoying but sometimes he's okay. Jeff Goldblum is adequate in a supporting role. Robin Williams's character seems forced.
While things are a little light and slow in the beginning, it's in the last half hour that the writer puts a little too many comedy, most of it falling flat on its 'face'. With a cast like this, one would have expected better. I'd still say it's far more enjoyable than the likes of 'Runaway Bride' and 'Pretty Woman'.
