The soulless fiancee
Notable offenders: "It Could Happen to You," "Something Borrowed"
In this 1994 Bridget Fonda-Nicolas Cage rom-com, the incomparable Rosie Perez is saddled with a character who's presented as a shrieking Puerto Rican stereotype with no other motivation but to get that money. Due to the racial component this just happens to be the most loathsome example of the "soulless fiancee" cliche -- gold-digging and/or just plain detestable characters who exist merely as a counterpoint to the klutzy, good-hearted protagonists. They're the rom-com equivalent of the mustache-twirling Bond villain.
