I had NO idea at the time... in fact, back then, I had NO idea it was even an "Agatha Christie"... but way, way back, I caught THE ALPHABET MURDERS when the network ran itr some weekend evening. Couldn't make heads or tails of it.
My "official" 1st AC film was DEATH ON THE NILE, which I saw in a theatre-- TWICE! Amazing how KNOWING every detail of the plot doesn't ruin that one-- it just turns it into a completely different movie. (I love that it is told SO clearly it is impossible to get confused... at least, once you've reached the end.)
My "1st" Miss Marple was THE MIRROR CRACK'D. I didn't know what to make of it. Saw that in a theatre (just lucky, it disappeared in 7 days flat). Funny but true-- I had NO IDEA Angela Landsbury was NOT really that old when she did it. Great make-up job.
Later I saw Helen Hayes (who I loved in THE SNOOP SISTERS in the 70's). What a sweet lady!
Joan Hickson took a long time to grow on me. I taped most of them as they premiered, but compared to POIROT, it wasn't doing it for me.
I can't recall exactly whe I taped the 4 Margaret Rutherford films, but I got all of them off commercial TV (and they may still have the commercials, I forget). Careless of me not to get better copies off TCM when I had the chance. I will say, they definitely got better the 2nd time I watched them.
Imagine my shock, after having seen those 4, to catch THE ALPHABET MURDERS again... and to realize Rutherford had a wordless cameo in it. Poirot is written as a FOOL in that film, and HER character clearly knows it!
The sheer irony is that when David Suchet finally did THE ABC MURDERS, it was, truly, one of the VERY BEST of the series. Wow. How does one take a story THAT good and completely murder it, as they did in the late 60's? It's just one of those films from a breif period when everyone in the film industry seemed to go completely nuts, throw out all the rule books, and any sense of logic. But on top of anything else, Robert Morley would have made a much better Poirot than he did a Hastings. Honestly!!)
I understand there's not one but TWO Miss Marple series since Joan Hickson... and blast it, I haven't seen any of them!!!
