The Prince and the Showgirl originally called The Sleeping Prince is a 1957 BritishAmerican romantic comedy film starring Marilyn Monroe and Laurence Olivier. Olivier also served as director and producer. The screenplay by Terence Rattigan was based on his 1953 stage play The Sleeping Prince. It was filmed in London.

The British government realises that keeping Balkan country Carpathia in the Triple Entente is critical during the rising tensions in Europe. They find it necessary to pamper the royals during their stay in London, and thus civil servant Northbrook is detached to their service. Northbrook decides to take the Prince Regent out to the musical performance The Coconut Girl. During the intermission the Prince Regent is taken backstage to meet the cast. He is particularly uninterested in engaging with the male actors and extremely interested in the physical charms of Elsie Marina, one of the performers, and sends a formal written invitation for her to meet him at the Carpathian embassy for supper.Elsie arrives at the embassy and is soon joined by the Prince Regent, a stiff and pompous man. She expects a large party but quickly realises the Princes true intentions to seduce her over a private supper. She is persuaded not to leave early by Northbrook, who promises to provide an excuse for her to escape after supper. The Prince Regent turns his back on her during supper, taking phone calls and addressing matters of state. He then makes a clumsy pass at her, to which shes accustomed and immediately rebuffs. She pointedly explains how inept he is and that she had hoped the Prince was going to sway her with romance, passion and gypsy violins. The Prince changes his style and tactics, complete with a violinist. The two eventually kiss and Elsie admits she may be falling in love, rebuffing Northbrooks promised feint to help her leave the embassy. Elsie then passes out from the many drinks she consumed before, during and after her semisolitary supper. The Prince places her in an adjoining bedroom to stay the night. ........
