You can’t go wrong with a retrospective of Ernst Lubitsch, whose movies still sparkle with urbanity and sly wit. Film Forum serves up a feast of them beginning Friday, June 2, in “The Lubitsch Touch,” which commemorates the 125th anniversary of his birth. The program, which runs through June 15, features 31 films, an array that demonstrates versatility and adaptability. Lubitsch, who died in 1947, began directing in the silent era but transitioned with apparent ease into talkies. For a sample of his style, you can’t do better than the 1940 comedy “The Shop Around the Corner” (showing June 3).

It stars James Stewart and Margaret Sullavan as shop employees who dislike each other but don’t realize they’ve been corresponding anonymously and flirtatiously. In the land of Lubitsch, jokes are slipped in subtly.

“How much is that belt in the window, the one that says $2.95?” a customer asks.

“$2.95,” Stewart’s character replies, somewhat baffled.

“Oh,” she says disapprovingly. “No.” And she walks out.
