[3] As the British Government had decided that keeping Carpathia in the Triple Entente is critical amid the rising tensions in Europe, they wish to pamper the royals during their stay in London and assign civil servant Northbrook for the task.

During the intermission, Charles meets the cast backstage and is smitten with performer Elsie Marina, to whom he sends a formal invitation for midnight dinner at the Carpathian embassy.

When Charles makes a clumsy pass at her, she immediately rebuffs him and explains that she had hoped that he would sway her with romance, passion, and "gypsy violins."

The two eventually kiss and Elsie admits that she may be falling in love, turning aside Northbrook's pre-agreed attempt to help her leave the embassy.

When Elsie passes out due to being encouraged to drink too much vodka, Charles has four servants carry her on their shoulders like a log into an adjoining bedroom, where she spends the night.

Sinden said: She was still suffering from the effects of the Method school of acting, so one day I had the props department make up a notice that I fixed to my door saying:

The film opened on 13 June 1957 at the Radio City Music Hall in New York and in Los Angeles and London on 3 July 1957.

[1] The Prince and the Showgirl was not a major box-office success, faring poorly in comparison to Monroe's earlier releases, such as The Seven Year Itch and Bus Stop.

[7] Variety wrote in its original review: "This first indie production of Marilyn Monroe's company is a generally pleasant comedy, but the pace is leisurely.

"[8] The New York Times stated that the film lacked originality and that Rattigan's characterizations were "too limiting" and "dull" to allow Monroe and Olivier to be showcased to their fullest potential.
