Rob Reiner’s sharp, talky comedy on the mating habits of modern men and women will always be remembered for a scene that wasn’t conceived by the director, whose frustrations with post-relationship dating inspired the film, or the screenwriter (Nora Ephron), who provided the balancing she-said ying to his he-said yang. It was plucky pixie Meg Ryan who came up with the idea of faking a wall-rattling orgasm in the middle of a crowded deli — attended by, among others, Billy Crystal and Reiner’s mother, Estelle — shattering the egos of not only her dining companions but overconfident men everywhere. Reiner, Ephron, and actors Billy Crystal and Carrie Fisher share other secrets behind their labor of love in a new 33-minute retrospective, the best of this disc’s comparatively bland extras (which do not include fresh input from Ryan). The director’s commentary is relatively sparse and repeats many of the documentary’s revelations, but in the end, who needs it? This sweet romantic fairy tale speaks for itself. B+
