- Executive Meddling: The killer was originally supposed to be Buzz, but the U.S. Navy objected to the idea of one of its service members committing a murder and persuaded the studio to have Chandler rewrite the ending.
- Those Two Actors: This was the third film to co-star Alan Ladd and Veronica Lake.
- Troubled Production: According to producer John Houseman, Chandler fell into "writer's block" on the last third of the script during shooting (possibly a euphemism for Creative Differences related to the above Executive Meddling), and straight-up said he couldn't finish it; he eventually wrote out the rest blind drunk, consuming almost nothing but alcohol (plus glucose injections from his doctor) for eight days. This anecdote is one of the most (in)famous surrounding Chandler and The Golden Age of Hollywood in general, but in modern times several people have cast doubt on whether all - or any - of it is true, as some of the dates and facts in Houseman's memoirs don't quite stack up to contemporary documents from Paramount.
