Evil Under the Sun is a must for any Peter Ustinov fan. As usual, he chews up scenery and is a lot of fun to watch.
It certainly helps also, if you're an Agatha Christie mystery book fan, and it helps even more if you're a fan of her detective character, Hercule Poirot. Which Peter Ustinov plays. Throw in an elegant old hotel on a beautiful resort island location set in the pre-war 1920s or 1930s, interesting guests, and an easy to understand storyline, and you get a really fun, good movie.
The other thing I like about Evil Under the Sun is that there are a LOT of renowned, great actors in this movie. And they all get it- this is a fun, almost campy movie. And they act down accordingly. And in doing so, you like this movie even more.
The final reveal about who murdered the one guest is fun to watch too. It's thoroughly explained, to include flashbacks to earlier scenes in the movie, to further help you understand the clue that Hercule Poirot is talking about. And for the final time, Peter Ustinov captivates the entire room. And you, the viewer!
So if you want a fun, well-filmed, well-acted movie, or, if you're a fan of Agatha Christie, her character Hercule Poirot, or of Peter Ustinov, watch Evil Under the Sun. You'll be glad you did.
