. A few months later, Wilder began dating Mary Joan Schutz, a friend of his sister. Schutz had a daughter, Katharine, from a previous marriage. When Katharine started calling Wilder "Dad", he decided to do what he felt was "the right thing to do", marrying Schutz on October 27, 1967, and adopting Katharine that same year. Schutz and Wilder separated after seven years of marriage, with Katharine thinking that Wilder was having an affair with his Young Frankenstein co-star, Madeline Kahn. After the divorce, he briefly dated his other Frankenstein co-star, Teri Garr. Wilder eventually became estranged from Katharine.
