Gabrielle Union will star in Tyler Perry's latest Lionsgate film, "Daddy's Little Girl." Written by Perry, the reverse-Cinderella tale centers on a successful attorney (Union) who falls in love with a janitor who is a single father of three children. This relationship causes a rift between the woman and her father, as he hoped she would marry wealthy. The film is being produced by Reuben Cannon and will shoot in the summer in Atlanta. Union most recently starred in ABC's short-lived series "Night Stalker" and next appears in "Running With Scissors." Other feature credits include "The Honeymooners," "Bad Boys II" and "Deliver Us From Eva." She is repped by UTA and manager Jeff Morrone.
