The Glass Bottom Boat Movie Review
I'm being a little cruel, yes, but Boat is a pretty thin picture anyway and it doesn't merit a whole lot of sympathy. The story involves a misunderstanding (imagine that!) wherein Day is mistaken for a spy. Eventually she plays the part (when she isn't busy romancing Rod Taylor), when she isn't stuck in compromising positions with Dom DeLuise and/or Paul Lynde.
This is pretty lightweight stuff, with a ridiculous slapstick plot that relies frequently on people getting body parts stuck where the don't belong, things getting knocked over, and Day rehashing some of her most notable songs from more successful movies. Well, as Day would say, que sera, sera.
