This is a fine romantic comedy. Sandra Bulluck is one of my favorite actresses and I end with some of the other moview I have really liked that feature her.
In a nut-shell, she plays a boss clearly related to Satan, and while Ryan Reynolds is her hapless assistant who becomes valuable when she suddenly needs a husband.
Ryan Reynolds is not a name I recognize, he was world-class in this movie, and would appear to be ready to move up from the fraternity silly movie genre.
Other films with Sandra Bullock I especially liked:
Two Weeks Notice (Full-Screen Edition) (Snap Case)
The Lake House (Full Screen Edition)
28 Days (Special Edition)
And of couirse there are others.
