Sam Wasson

Wasson was born in Los Angeles. His maternal grandfather was former Variety executive Hal “Lew” Scott. Wasson attended Wesleyan University, and USC School of Cinematic Arts.

During the writing of his Bob Fosse biography, Wasson and researcher Jane Klein unearthed lost footage of Fosse's 1961 ABC television show Seasons of Youth. In 2014, Fosse was one of six books shortlisted for the $10,000 Marfield Prize, and received the Special Jury Prize at the George Freedley Memorial Award. Production rights for a limited television series based on the book were purchased by television channel FX in 2018.

In 2020, Wasson published a book about the making of the 1974 movie Chinatown, titled The Big Goodbye: Chinatown and the Last Years of Hollywood. Later that year, a film adaptation of The Big Goodbye was announced, with Lorne Michaels attached as producer and Ben Affleck as director. Also in 2020, Wasson co-founded a publishing house with producer Brandon Millan.

Wasson was a visiting professor at Wesleyan University and Emerson College.

In 2021, Wasson and William Rempel filed a lawsuit to unseal a 2010 deposition transcript of Roger Gunson, a former deputy district attorney, in relation to the Roman Polanski sexual abuse case. In July 2022, the court ruled for the transcripts to be unsealed.

In 2022, Wasson and Jeanine Basinger wrote an oral history book titled Hollywood: The Oral History.
