HOLLYWOOD - Brooke Langton, who most recently played Keanu Reeves' love interest in football feature "The Replacements," is a big girl now. The actress has been tapped to star in the tentatively titled Fox series "When I Grow Up."
     Langton stars as twentysomething Elizabeth Gillcrest, whose life is turned upside down when her older husband discovers she is having an affair. Her character ends up at a "Tempt-a-Mate" firm working with the man she had the affair with.
     Focus of the new series is reminiscent of creator Glenn Gordon Caron's hit 1980s romantic comedy "Moonlighting" which also featured a young couple, Cybill Shepherd and Bruce Willis, who worked together.
     The new one-hour romantic comedy will go into production shortly to complete its 13-episode order before the start of potential strikes by writers and actors next spring and summer.
