Two of A Kind | 1998
Mary Kate and Ashley Burke are pre-teen identical twin sisters who are complete opposites. Mary Kate is a tomboy whose biggest interest is perfecting her curveball. Ashley is a straight-A student starting a boy-crazy phase. They live with their dad, Kevin, a science professor and single father. When Carrie Moore, a 28-year-old freshman in Kevin's seminar answers his ad for a part-time nanny, he is convinced she's nothing but trouble. The girls think she is a dream-sitter come true and agree to put their differences aside and join forces to make a little chemistry between their by-the-book dad and the beautiful woman who seems to drive him crazy in all the right ways.
