Writers Joel Coen and Ethan Coen suffered writer's block while writing Miller's Crossing (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. Byrne argued that his dialogue was structured in such a way that it was a good fit for his accent, and after he tried it, the Coens agreed. Ultimately, both Byrne and Albert Finney used Irish accents in the film.
The character Eddie Dane was originally written for Peter Stormare and was to be named The Swede. Stormare had to decline as he was appearing as Hamlet in the Broadway production. The part was then re-written and re-cast, and became The Dane.
