Wet scenes in movies

Does anyone remember a Peter Sellers film called 'The Party' from about 1968? Its full of wet scenes and I reckon that everyone in the cast ends up in the water, wearing mostly formal gear, at various times during the action. I had forgotten about it until I found a huge pile of video tapes after a house move last year, and decided to look through them all while my ancient videotape machine still works! As a bonus for lovers of vintage motors there is a lovely 'Morgan' 3-wheeler as well.
