Writers Joel Coen and Ethan Coen suffered writer's block while writing Un cadavre sous le chapeau (1990). They took a three week break and wrote Barton Fink (1991) a film about a writer with writer's block. The name of Tom Regan's residence is "The Barton Arms". In one of the newspapers an article reads 'Seven Dead in Hotel Fire,' another reference to Barton Fink.
In the script, the film takes place in 1929.
Although he was a native Irishman playing a lieutenant to an Irish mobster, the Coens did not originally want Gabriel Byrne to use his own accent in the film.

Ultimately, both Byrne and Albert Finney used Irish accents in the film.
Bernie is referred to as a Schmatte. 'Schmatte' is a Yiddish word for an old rag and was also used colloquially as a label for things of poor quality or anything worthless. Caspar's use is derogatory, labeling Bernie worthless both as a man and as a Jew.
