Which version do you prefer?

Of the ones I've seen(1945, 1966, 1974),my favorite is the 1966 version, mainly because I'm a Bond fan and I like seeing "Golden Girl" Shirley Eaton in one of her few starring roles. I also the rest of the cast(Stanley Holloway, Daliah Lavi, Wilfrid Hyde-Whyte, Dennis Price)and the British "feel" which seems appropriate for a screen adaptation of a Christie work. I haven't seen the Russian version or the 1989 one yet.
