The $3,000 "Calcutta" ticket Marilyn buys for Kelly to win the golf match would be the equivalent of $43,300 in 2016.
The Lake Norconian Club, where the golf scenes were filmed, opened c.1928 and was a favorite of Hollywood and other celebrities. Several other films were shot at the club, including Walking on Air (1936) and Test Pilot (1938). It closed in 1933 due to the Depression, but opened again in 1935 after additional funding was secured, but closed again for good as a resort in 1940. In late 1941 it became a U.S. Navy Hospital and the facility was expanded to care for over 5,000 patients at once. The hospital closed in 1957. The California Rehabilitation Center opened on the site in 1962. The main resort building was abandoned in 2002 due to earthquake safety codes, and as of 2020 it remains empty and crumbling away.
The play, "Spring Fever," opened on Broadway in New York City, New York, USA on 3 August 1925 and closed in September 1925 after 56 performances. The opening night cast included James Rennie in the lead.
"Like Kelly Can" by Dorothy Fields and Jimmy McHugh was written for the movie but not used in the release print.
