In 1989, director Rob Reiner was just starting to make people forget actor Rob Reiner (Meathead from “All in the Family”) when he created a cinematic standard for romantic comedies. Helped by an all-star team (writer Nora Ephron, cinematographer Barry Sonnenfeld, stars Billy Crystal and Meg Ryan), Reiner’s “When Harry Met Sally” is the Woody Allen movie for everyone who doesn’t like Woody Allen movies, a Manhattancentric look at Baby Boomer relationships with romance and pathos leavened by cunning wit. Crystal and Ryan are the friends who think friends can’t be lovers (or is it vice versa?) until they are.
