Diane Lane stars as the horse’s owner Penny Tweedy, the housewife who broke though a gender barrier to usher Secretariat to greatness. Walsh plays Lane’s husband, a successful attorney who is accustomed to his wife being at his beck and call. Malkovich plays a charismatic trainer who underestimates the power of Secretariat; Glenn is a southern-bred aristocrat who loses the horse in a coin toss. Randall Wallace is directing from a script by Mike Rich.
