Ross Hunter liked to develop new talent and the movie features 23 actors who had never made a film before.^[5] Among them was Peter Fonda, who had enjoyed critical acclaim for his performance in Blood, Sweat and Stanley Poole. Hunter signed Peter Fonda to a seven years contract.^[6] Filmink magazine argued Fonda at this stage of his career was "a sort of poor man’s James Stewart – tall, gangly, boy next door, virginal looks, etc. (And Stewart was, famously, best friends with Fonda’s father, Henry)."^[7]
