Evil Under the Sun is Peter Ustinov's best turn as Agatha Christie's Hercule Poirot in this second episode of the series. It's simply fascinating. An all-star cast -- including Colin Blakely, Jane Birkin, Maggie Smith, Roddy McDowall, James Mason, and Diana Rigg -- comprise the eccentric round of suspects in a murder that's been committed on a remote vacation isle. The mystery is a devious one; Poirot has to sort through all kinds of secrets and clues and devilish plans to figure it all out -- and yet it all makes sense. Director Guy Hamilton paces the film well and knows how to build dramatic tension. At the end, is there anything more satisfying than nabbing the criminal mastermind behind it all?
