Edward Everett Horton

Writer and notorious marriage detractor Mortimer Brewster (Cary Grant) falls for girl-next-door Elaine Harper (Priscilla Lane), and they tie the knot on Halloween. When the newlyweds return to their respective family homes to deliver the news, Brewster finds a corpse hidden in a window seat. With his eccentric aunts (Josephine Hull, Jean Adair), disturbed uncle (John Alexander), and homicidal brother (Raymond Massey), he starts to realize that his family is even crazier than he thought.

When the draft selects rock star Conrad Birdie, his fans are devastated, but none more than struggling songwriter Albert Peterson (Dick Van Dyke), whose song Birdie was just about to record. Albert's longtime girlfriend, Rosie (Janet Leigh), pushes Albert to write a new tune that Birdie will perform on television to a fan selected in a contest. The scheme works, with young Ohio teenager Kim McAfee (Ann-Margret) declared the winner, but no one has counted on the jealous wrath of her boyfriend.
