Schumacher envisioned the character of Star as being a waifish blonde, similar to Meg Ryan, but he was convinced by Jason Patric to consider Jami Gertz, who had just worked with Patric in "Solarbabies" (1986). Schumacher was impressed, but only at Patric's insistence did he finally cast Gertz. Schumacher was surprised when his first choice for the role of Lucy, Dianne Wiest, accepted the role, as she had just recently won the Academy Award for Best Supporting Actress for "Hannah and Her Sisters" (1986).
