You gets what you pays for in An Alligator Named Daisy. Donald Sinden stars as a young songwriter who accidentally picks up someone else's alligator suitcase. Somehow this leads to the luckless Sinden being saddled with a baby alligator, who prefers to sleep within his piano. Glamour girl Diana Dors is the leading lady, revealing an unexpected flair for wacky comedy. Based on a novel by Charles Terrot, An Alligator Named Daisy seemed to show up every other day on TV in the early 1960s, possibly due to its pleasant Technicolor photography.
