 When Penn saw her scenes from "The Happening" before its release, he decided to let her read for the role of the bank robber Bonnie Parker for his upcoming film, "Bonnie and Clyde" (1967).Casting for the role of Bonnie had proved to be difficult and many actresses had been considered for the role, including Jane Fonda, Tuesday Weld, Ann-Margret, Carol Lynley, Leslie Caron, and Natalie Wood.Penn loved Dunaway and managed to convince actor and producer Warren Beatty, who played Clyde Barrow in the film, that she was right for the part.
