It is an old cliche that the movie seldom does justice to a book, but this version takes the book, cuts it into little bits and then stamps all over it. For those who have read (and reread and loved) the book, this adaptation will come as a deep disappointment as it simply rewrites its own plot. Colourful characters like the Harmons have been wiped out of the script, events that build the plot have been illogically mangled (here Sgt. Fletcher never discovered the oiled door!), Col. Easterbrook's character has been dolefully smeared, his muddled but affectionate wife has been replaced with an unconvincing love interest (that has no relevance to the plot and no time to develop anyway) and to the dismay of Christie fans, the dramatic end scene where Lotty attempts to murder Mitzi has been completely reversed into the other way round! Totally unconvincingly, I may add - after all, Mitzi may be foreign, volatile, hysterical and all that, but not a cold-blooded knife-wielding motiveless murderess! I have to ask bitterly, just who are these script writers who think they can take on the venerable Dame's skilfully woven tapestries, patchwork the material with shears and sellotape and profit from her name? Yes, yes, the period effects are excellent, some of the acting creditworthy and the mood well captured. But for all that, regrettably, dear reader, this one is for the trash can.
