Weddings are supposed to be about joy and harmony, but the reality is, uniting two families is a complex negotiation, a diplomatic and tenuous situation, and rife with the opportunity for drama, comedy, and if you’re lucky, a good spot at the smorgasbord. For instance, take Leah Lowenstein’s wedding to Sam Levine. Leah’s a nice Bais Yaakov girl from a religious family; Sam’s in a rock band. Sam’s mother, Dr. Roz, has a popular radio advice show, but she has an awful relationship with Sam’s father, Morty. Dr. Roz has hired her “hippie rabbi,” Conrad Singer, to perform the wedding, unbeknownst to the Lowensteins, who have employed Rabbi Perl, a more traditionally Orthodox rabbi. The dysfunction flows like Baron Herzog into the glass of hyperactive, almost too-happy bridesmaid, Gitti Sara, who’s so desperate to get married that she solicits dates from the guests. Most of them just ignore the histrionics, turning their attentions to the kosher Moroccan-style buffet. Maybe you need a Jewish wedding refresher course. Or you’re sick of attending weddings. Or you’re considering a career as an Owen Wilson/Vince Vaughn-style wedding crasher. “A Match Made in Manhattan” is a chance to attend nuptials where no one cares how you behave — as long as you participate in the simcha, and play Jewish geography until you find someone you know.
