All In a Night's Work

Dean Martin thinks that Shirley MacLaine was the mistress of a recently deceased millionaire. On this fragile plot peg hangs the rest of All in a Night's Work. The millionaire died with a smile on his face, and Martin, who stands to inherit the dead man's publishing business, suspects that MacLaine, who has been left a fortune, administered the favors that pushed the old coot into the Great Beyond. MacLaine, wholly innocent, resents Martin's implications and gives him the brush-off. All turns out for the good when Martin realizes that he loves MacLaine for herself and not for her legacy. It took three writers (five, if you count the authors of the play upon which this film is based) to cook up the tickle-and-tease souffle that we've come to know as All in a Night's Work.
