The play opened in London, England on 3 March 1921. It opened on Broadway in New York City on 12 September 1921 and closed in February 1922 after 175 performances. The opening night cast included John Halliday as Ted, Estelle Winwood as Elizabeth and Walter Soderling as the Butler. There were 2 revivals of the play: in 1938 with Tallulah Bankhead and John Emery, and in 1989, with Stewart Granger, Rex Harrison and Glynis Johns.
When it was originally released in April 1930, Strictly Unconventional ran 72 minutes, but, by the time it found its way to New York City in July 1930, (for a one day showing on a double bill at Loew's), MGM had cut it to 54 minutes, and this is the version which survives today on Turner Classic Movies.
