Ustinov as Poirot - terrible
Suchet as Poirot - beautiful
whoever played his sidekick- great
Also, Whately who played Lewis is great
Any of those females who played Ms. Marple - dreadful! none of them came anywhere near her character.
Lou Diamond Phillips as Jim Chee (Hillerman) - pretty good
I don't know all the British actors, but some of the Mystery! series were very well done.
Didn't think the guy who played Hamish McBeth did a good job. He was the guy in The Full Monty.
