Soon after Ostrum returned home from filming Willy Wonka, his family acquired a horse; while the teenaged Ostrum was interested in the horse, it was the animal's veterinarian that left a lasting impression on him. Taking a hiatus from school between high school and college, Ostrum groomed horses and worked at the Delaware Equine Center in Pennsylvania. Ostrum contemplated a return to Hollywood, and even visited California for a week to "test the waters" there.
