Whoa! What's that smell?
Oh yeah. It's this movie.
Whew! What a stinker. And it looks like it's all the director's fault, Michael Winner. With some serious help from the editor, but upon checking I see he edited it himself.
This is a pretty fine cast, at least of the main characters, people who can really act. But here they're made into a bunch of overemoting hams by Winner.
I was looking forward to an interesting Agatha Christie mystery, and all I got was a bunch of disjointed shouting and dubbed-in-later lines that didn't even help explain the feeble plot. I wouldn't have thought you could take a Christie story and make it into a nearly unfathomable jumble, but Winner did it.
Too bad.
