Trivia

The film was previewed with five different endings and the existing one (a complete departure from the play) was selected for reasons of popular response and censorship, prompting the resignation of producer Joan Harrison from Universal Pictures. She left with two more pictures left on her contract.

Harry's line about home references Robert Frost's The Death of the Hired Man: "Home is the place where, when you have to go there/ They have to take you in."

Moyna MacGill, who plays the older sister, is Angela Lansbury's mother in real life.

Richard Murphy, production manager at Universal, previewed a version of the film with an alternate ending. He worried that the railroad station epilogue in Siodmak's version would be open to attack by the PCA, as it shows Harry and Deborah's reunion before he commits himself to a mental hospital, which he believed morally dubious. Despite Joan Harrison and Siodmak's objections, Universal imposed Murphy's facile ending that was completed by director Roy William Neill with Sanders and Raines. Geraldine Fitzgerald refused to participate.

"Theater Guild on the Air" broadcast a 60-minute radio adaptation of the movie on May 18, 1947, with Geraldine Fitzgerald reprising her film role.
