Stan Laurel was ill during filming, appearing pale and tired.
Film Daily-Friday 11 August 1939: Plagiarism suit for injunctions, accounting and damages was filed in (Los Angeles) Federal Court yesterday by Isabella Knotter against Hal Roach Studios, Inc., Metro-Goldwyn-Mayer Pictures Corp., M-G-M Distributing Corp., Lowes, Inc. and Culver Export Service. Plaintiff claims to have submitted her story, "So Zwei Pechvogel." or "Two Down-and-Outs," to the Hal Roach studios on June 16,1937, which was allegedly infringed in the films "Swiss Miss" and "Au Far West." Her manuscript had been returned in August, 1937, with a notation stating that it had been unread, the complain stated.
Rumoured to have been filmed in Colour, but the film was processed into Black and White. Close examination of the Black and White film quality compared to similar Laurel and Hardy features of that time possibly suggest this but so far a colour print has not surfaced. The film was idea for colour testing due to the sets costumes and even the title lettering used.
The gorilla is played by actor 'Charles Gamora', who also played Ethel the chimp in an earlier L&H short The Chimp.
This film has a famous comedy scene with Laurel and Hardy trying to move a piano across a bridge suspended high above some mountains. Originally, there was to have been a subplot in which a bomb had been secretly attached to some keys in the piano, thus adding suspense to the comedy. Producer Hal Roach deleted the bomb subplot but retained the now-pointless shots of Laurel accidentally hitting the piano keys.
