In Lynn Shelton’s new film Laggies (in select theaters October 24 and nationwide November 7), Keira Knightley plays Megan, a sweet but slackerrific 28-year-old whose total lack of motivation utterly stumps her friends and family. At a time when all her friends are embracing their adult responsibilities, Megan would much rather hang out with her new teenage friend Annika (Chloe Moretz) and refuse to grow up, and nowhere is that enthusiasm gap more evident than when Megan is forced to celebrate the imminent wedding of her prissy friend Allison (Ellie Kemper). In this exclusive clip from the film, Megan treats a bachelorette party game as the impetus for an immature (but enjoyably scandalous joke), but Allison is not having it. A very unique cockfight then ensues, with Knightley and Kemper pitted head to head.
