Kate Hudson was pregnant during part of the filming. Near the end of the movie, she subconsciously touches her midriff as she walks.
While filming, director Garry Marshall kept referring to Kate Hudson as "Goldie". He had worked with Hudson's mother Goldie Hawn on Overboard (1987) and kept getting the name wrong, as he said they looked and acted so much alike.

By the end of the shoot, the money in the box provided for a lavish party, thrown by Hudson for the entire crew.
