No matter how old you are, you never get over high school. "You Again" is an outrageous comedy featuring an all-star female cast, including Kristin Bell, Jamie Lee Curtis, Sigourney Weaver, Odette Yustman, Kristin Chenoweth and Betty White. Bell stars as Marni, a successful PR pro who discovers that her brother is marrying her high school arch nemesis—and, to make matters worse, Marni’s mom recognizes the bride’s highfalutin aunt as her own high school rival.
