Note when the stranded motorist says he has trouble with his distributor, and Orson Welles ironically, and maybe sarcastically, says he also has trouble with his distributor as well - meaning film distributor. He was having financial difficulties making Othello (1951) at the time, so this is probably an inside joke.
The film was given to RCA Recording Studios in Hammersmith to complete post-production. They engaged Joseph Sterling to edit it. When the film arrived, it had been very roughly assembled by someone not used to cutting room procedure: trims tightly wound up, no identification, etc. Originally, the film's commentary was given by Michael Laurence, who played Sean Merriman. When editing was completed, Hilton Edwards ran the film for Orson Welles. He then decided that he should redo the commentary.
The inscription in the cigarette case is from the Bible - Song of Soloman 2:17, King James Version.
The opening and closing credits are accompanied by a full orchestra, but the film proper is scored with only a harp.
"Glennascaul" is Irish for "Glen of the Shadows."
