After seeing her 1973 film debut in Blume in Love, Neil Simon cast Mason in his Broadway play The Good Doctor.[1] Shortly afterwards, Mason and Simon, a widower, fell in love and got married. That same year, Mason co-starred opposite James Caan in the 20th Century Fox film Cinderella Liberty, which netted her an Oscar nomination for Best Actress. In 1977, Mason's performance in Simon's smash hit film, The Goodbye Girl, won her a second Best Actress Academy Award nomination. In 1979, Simon successfully cast Mason as Jennie MacLaine in the screen adaptation of his hit play Chapter Two, which was based on Mason's relationship with Simon up to their marriage. The film proved to be another big hit, garnering her a third Oscar nomination for Best Actress.[citation needed]
