Carl Foreman (High Noon) High Noon

Carl Foreman wrote the screenplay for High Noon while being investigated by HUAC. He adapted John W. Cunningham's short story "The Tin Star" (published in Collier's magazine in 1947), but by the time he was writing the actual script in 1951, his own life had become the story. He was blacklisted before the film opened and forced out of the country before he could see what the film became. (wikipedia)

Foreman started writing about collective action and ended up writing about abandonment

Foreman began outlining the screenplay in 1946 as a post-World War II parable about the need to stand together against aggression -- an argument for the United Nations and international cooperation. By 1951, that idealism was gone. He had received a subpoena from HUAC, and the allegory shifted from global politics to the Hollywood community's failure to protect its own.

"As I was writing the screenplay, it became insane, because life was mirroring art and art was mirroring life. It was all happening at the same time. I became that guy. I became the Gary Cooper character." -- Carl Foreman, Vanity Fair (2017)

The marshal going door to door asking for deputies was the screenwriter watching his colleagues in Hollywood make calculations about career survival versus solidarity. Every reasonable refusal Kane receives -- the mayor's pragmatism, the judge's self-preservation, the retired marshal's cynicism -- came from conversations Foreman was having with people who agreed he was right but would not stand with him.

He refused to name names and was thrown to the wolves

Foreman testified before HUAC as an "uncooperative witness." He admitted to having joined the Communist Party more than ten years earlier as a young man, but had become disillusioned and quit. He refused to name other members. The response was swift.

"They threw me to the wolves." -- Carl Foreman, Splice Today (2017)

Stanley Kramer, his producing partner, pressured him not to plead the Fifth Amendment, fearing it would damage their company. When Foreman refused to cooperate fully, Kramer forced him to sell his share of the production company. John Wayne, working through the Motion Picture Alliance for the Preservation of American Ideals, helped push Foreman out of the industry entirely. Wayne later said he would "never regret having helped run Foreman out of this country." (splicetoday, wikipedia)

Zinnemann, Cooper, and a bank loan kept him on the picture

When Kramer tried to remove Foreman from High Noon during production, director Fred Zinnemann and star Gary Cooper intervened. An outstanding Bank of America loan also helped -- Foreman had not yet signed certain papers, and removing him would have complicated the financing. He finished the screenplay, but the damage was done. His name was eventually removed from the credits of some prints. (splicetoday)

He spent 25 years in exile writing under pseudonyms

Foreman moved to London before High Noon was released. He was blacklisted and could not work in Hollywood under his own name. He wrote screenplays under pseudonyms for 25 years, including an uncredited contribution to The Bridge on the River Kwai (1957) -- a film that won the Academy Award for Best Adapted Screenplay. Foreman did not receive proper credit for that work until decades after his death. (wikipedia)

He returned to Hollywood eventually, but never recovered his former position. He died in 1984. The allegory he embedded in High Noon outlived him -- and outlived the political context that inspired it. The film's question -- what happens when your community abandons you -- has been claimed by presidents, dissidents, and whistleblowers across the political spectrum, none of whom remember that the man who wrote it was blacklisted for asking it.
