Comparing POIROT versions... (just posted at the IMDB)
Unfortunately, most of the Suchet "remakes" I haven't seen yet... (DAMN!)
However... I just watched THIRTEEN AT DINNER and LORD EDGEWARE DIES back-to-back. WOW. The Ustinov version is loud, garish, annoying, yet fun. The updating didn't bother me that much because-- let's face it-- we've seen updates in so many of those Basil Rathbone HOLMES films, Roger Moore SAINT episodes, and every single JAMES BOND film ever made! If anything, it was the attitude of some of the American characters that got on my nerves, and all the time spent with them and the movie crew took away time from solving the murder properly. There were a few points that seemed to come out of left field, as if something was missing. Like, how did Poirot get ahold of the letter? What the HELL was the significance of the glasses? By comparison, with Suchet, it was a joy to see so much focus on the reunion of the main cast (even if this was not in the book, well, I'll admit the awful truth-- I have never read a single AC book!!). The unfolding of several key plot points-- like Poirot's talk with Lord Edgeware, where he wonders HOW is it possible the man's wife DIDN'T know he'd changed his mind, and several of the red herring motives were all spelled out much clearer in the Suchet version.
I've seen LORD EDGEWARE DIES now at least twice (or 3 times, but I'm not sure). It might have been better if I hadn't seen the Ustinov version the night before, but having done so, the Suchet version was ASTONISHINGLY well-done! The ending, instead of being brash, was jaw-dropping, as detail after detail slowly comes out, and you see the horror in Jane's intended's face, while inwardly, we feel the PAIN of Poirot, for surely, he was taken with her, even if he would NEVER admit it.
DEATH ON THE NILE and EVIL UNDER THE SUN are 2 of my favorite films of all time, period... so it'd be tough for anything to beat them. I'd still like to see the remakes. As for ...ORIENT EXRPESS, despite it being so high-profile and a huge success, I never cared for it that much. I know it's nuts, but I actually enjoyed the Alfred Molina version BETTER.
And then there's THE ABC MURDERS, which I've read is thought of as one of the best AC stories ever. The Suchet version lived up to its reputation. On the other hand, I watched the Tony Randall version again a couple weeks ago. I wanted to like it so much... it's got so MANY actors I know and like in it... but Randall is SOOOOOO BAD in it, and like too many "insane comedies" of the 60's, the storytelling seems designed to be as indecipherable as possible. When the bit from the very start of the film about the high-diver comes back to bite you at the end, it was a shock. Up to then, I didn't think the writer was paying attention to what he was doing AT ALL.
