There have been several versions including 2 Russian versions and an uncrediteed Indian version, these filmsa have starred Shirley Eaton, Oliver Read, Herbert Lom, Gert Frobe, Fabian, Charles Aznavour and Richard Attenborough although I don't know who appeared in which film I do know that Fabian appeared in a Black and White Film and Shirley Eaton, Oliver Read Charles Aznzvour and Richard Attenborough all appeared in the same film and Gert Frobe and Herbert Lom appeared in thew same film.

Gert Frobe also played Goldfinger in the movie of the same name on 1964. PS Goldfinger was banned in Isreal for many years because Gert Frobe used to be a NAZI! I know this isn't about Christie in any way but I'm also a massive Bond fan and wanted to share my wide but useless knowledge. Thanks

The Rene Clair version is the most faithful English-language adaptation. The others include:

1960s: Wilfrid Hyde-White (Pickering in My Fair Lady), Leo Genn, Stanley Holloway (Alfie Dolittle in My Fair Lady), Dennis Price, Shirley Eaton (Jill Masterson in Goldfinger), Hugh O'Brian, Fabian, Daliah Lavi, Mario Adorf, Marianne Hoppe star, set in a mansion in the Alps

1970s: Richard Attenborough, Herbert Lom (commish in Pink Panther movies), Alberto de Mendoza, Elke Sommer (A Shot in the Dark), Oliver Effin' Reed, Gert Frobe (Goldfinger in Goldfinger), Adolfo Celi (Largo in Thunderball), Charles Aznavour, Stephane Audran star, set in a hotel in the Middle East

1980s: Frank Stallone (Sylvester's bro), Donald Pleasence (Blofeld), Herbert Lom (again!), Brenda Vaccaro star, set on safari in Africa

I remember seeing the 1970's version many moons ago and really didn't like it. I don't think I have seen either of the other versions mentioned by Santonix, but my memory isn't the best!

However, I do remember seeing the 1945 Rene Clair film many times and loving it! I am a real sucker for b/w movies from the 30's and 40's so it's not surprising this one captured my imagination. The overwhelming claustrophobic feeling of being trapped and hunted (by their own pasts as much as a real live flesh and blood person bent on revenge and/or justice) sends shivers up my spine! I must try to get hold of a copy as it's a few years since I last saw it.

There you go Puffinjill!

They got worse with each decade. The one from the 60s had some really hammy acting, and the murders occured on an almost comic pace. Plus, every murder but the last ones are shown onscreen, so the ending is really easy to spot.

The 70s one was worse. Although I liked Attenborough (I just can't find any dirt on him as an actor), the entire cast was dreadful. Don't be fooled by names like Herbert Lom (who was actually in Murder at the Vicarage, which was a pleasant surprise!) and Gert Frobe-- the acting was dreadful, and this was basically the exact same as the 60s version with minor alterations for name/setting changes.

The 80s one I have yet to see. But judging on its reputation, don't waste your time. The trailer was enough for me- everyone seems to need acting lessons.

Everyone seems to have forgotten the amazing Russian adaptation, though, Desyat Negrityat. I can still see Emily Brent throwing her Bible through the window...

Thanks for that TheButlerDidIt, but I'm missing a bit of the link! Could you post it again sometime? Ta ever so!

Bless you! I'll check it out!
