It's a mystery

It's a mystery... well, they all are. Over the years there's been multiple remakes of Agatha Christie's movies. I've enjoy them all. My favorites were the remakes that stared Peter Ustinov. The latest remake stars Kenneth Branagh as the famous sluth Hercule Poirot. 
I really enjoyed Murder on the Orient Express,  and am looking forward to Death on the Nile,  now set to release February 2022.
