Sunset Boulevard was the last collaboration between Wilder and Brackett. They parted amicably and did not publicly air any grievances for the rest of their lives. In later years, Brackett confided in screenwriter/director Garson Kanin that he had not anticipated the split, or had ever understood exactly what happened or why. He described it as "an unexpected blow" from which he never recovered fully; when asked to respond to Brackett's comments, Wilder remained silent.[62]
The two men briefly reunited in October 1951 to face charges that they had plagiarized Sunset Boulevard. Former Paramount accountant Stephanie Joan Carlson alleged that in 1947 she had submitted to Wilder and Brackett, at their request, manuscripts of stories, both fictional and based on fact, she had written about studio life. She claimed that one in particular, Past Performance, served as the basis for the Sunset script, and sued the screenwriters and Paramount for $100,000 in general damages, $250,000 in punitive damages, $700,000 based on the box office returns, and an additional $350,000 for good measure, for a total of $1,400,000. Carlson's suit was dismissed after two and a half years. In 1954, a similar suit was filed by playwright Edra Buckler, who claimed material she had written had been the screenplay's source. Her suit was dismissed the following year.[63]
Brackett's Hollywood career continued after his split with Wilder. He won an Academy Award for his screenplay for Titanic (1953), and wrote Niagara (1953), the breakthrough film for Marilyn Monroe as a dramatic actress. It was Wilder, however, who realized Monroe's comedic abilities in The Seven Year Itch and Some Like It Hot. Brackett's career waned by the end of the decade, though he did produce the Oscar-nominated film The King and I (1956). He received an Honorary Oscar for Lifetime Achievement in 1958.
William Holden began receiving more important parts and his career rose. He won the Best Actor Oscar for Stalag 17 (1953), also directed by Wilder, and by 1956 he was the top box-office attraction in the United States. Holden and Wilder also rejoined forces for Fedora (1978), another film critical of Hollywood.
Before the film was released, Nancy Olson had grown disenchanted with film as a career partly because the themes of Sunset Boulevard resonated with her, and also because she had become engaged to songwriter Alan Jay Lerner and decided to move to New York with him. Nevertheless, Olson's pairing with William Holden was considered a success, and she appeared opposite him in several films during the 1950s, although none of them repeated their earlier success; she returned to Hollywood to make several other films, including The Absent-Minded Professor (1961) and Son of Flubber (1963), in which she was paired with Fred MacMurray.[23]
Similarly, Gloria Swanson was not able to leverage her own success in Sunset Boulevard. Although offered scripts, she felt that they all were poor imitations of Norma Desmond. Imagining a career that would eventually reduce her to playing "a parody of a parody," she virtually retired from films.[5]
Sunset Boulevard was shown again in New York City in 1960, and drew such a positive response that Paramount arranged for a limited re-release in theaters throughout the United States.
Films that discuss Sunset Boulevard in their screenplays or pay homage in scenes or dialogue include Soapdish (1991), The Player (1992), Gods and Monsters (1998), Mulholland Drive (2001),[7] Inland Empire (2006) and Be Cool (2005). The ending of Cecil B. Demented (2000) is a parody of Sunset Boulevard's final scene.
