Will Smith's future wife 'Jada Pinkett-Smith' auditioned for a role of his girlfriend, Lisa, on his show, but was told she was too short.
Ep. 26 The Philadelphia Story As the fourth season of the show was finishing, it wasn't clear if Will Smith would return to the show for a fifth season. Due to the uncertainty, the season finale ends with Will staying in Philadelphia for an uncertain amount of time. As he returned and made two more seasons, Smith's character is shown to have stayed in Philadelphia for a matter of weeks. Had Smith not returned, the finale would presumably be interpreted so that he moves back to his old neighborhood.
