Once, "The Lubitsch Touch," was as well known as Hitchcock's reputation as "The Master of Suspense."
"Trouble in Paradise" is Lubitsch's unqualified masterpiece. This pre-code sophisticated comedy epitomizes the European attitude toward sex in its very first scene between Hebert Marshall and Miriam Hopkins. Marshall reveals he has stole Hopkin's garter without her knowing it and she leaps in his lap. She checks -- at the dinner table no less -- realizes it is gone and with the admiration of one thief for another leaps into his lap. "Darling!" she says. No one has to guess what she has in mind, although it is all done with the wit and brio that the "Lubitsch Touch," refers to.
It's great to have this film readily available and the DVD version includes an informative and enlightening commentary (Marshall only had one leg and his lurching walk made a certain speedy cutting necessary that helps give the film it's light, speedy quality).
Lubitsch also made "Shop Around the Corner," remade by Nora Ephron as "You've Got Mail," and "Ninotcha," with Greta Garbo. His musicals with Maurice Chevalier and Jenette MacDonald, such as "The Merry Widow," are also worth seeking out.
