"[4] The film starred Marlon Brando and Sophia Loren, and revolved around an American diplomat who falls in love with a stowaway on a cruise.

The story is based loosely on Russian singer and dancer Moussia "Skaya" Sodskaya, whom Chaplin met in France in 1921.

Ogden dislikes the situation, being a married man although seeking a divorce, and he worries how it might affect his career if she is found.

Ogden's wife Martha arrives in Honolulu to join the cruise, under advice from Washington that they avoid the impropriety of a divorce.

Ogden's lawyer friend Harvey, who helped arrange the marriage, meets Natascha ashore and tells her that the immigration officers have accepted her as Hudson's wife, and she will remain in Honolulu.

Hong Kong actor Richard Ng had a minor walk on role in this film and during his early acting career in the UK in the 1960s.

[6] The idea, according to a press release written by Chaplin, "resulted from a visit I made to Shanghai in 1931 where I came across a number of titled aristocrats who had escaped the Russian Revolution.

"[7] Chaplin had written a draft of the script in the 1930s under the working title The Stowaway, as a starring vehicle for his then-wife Paulette Goddard.

[5] However, amidst work for The Great Dictator, Goddard signed a contract with Paramount Pictures, and left Chaplin the following year.

[9] For the character of Ogden, he originally wanted Rex Harrison or Cary Grant to play the role, but eventually Marlon Brando was cast.

[9] Tippi Hedren, who broke with Alfred Hitchcock, also signed on for the film without reading the script, and was disappointed to learn the insignificance of her role.

Although Chaplin tried to accommodate her, he could not, as the story mostly takes place on a ship that Hedren's character boards near the end of the film.
