David Suchet Reflects on 25 Years as Poirot - NYTimes.com - I agree - he is the definitive Poirot. He fit my vision of Poirot from reading all Agatha Christie's mysteries and I have loved his portrayal from the first episode.
A big thank you to the anonymous commenter who alerted me - here's the first promotional photo for The Big Four! It's amazing to see the 'Big Four' (Poirot, Hastings, Japp, Miss Lemon) back together again! Source: http://www.cyfraplus.pl/ms_galeria/fotobase/41551_c.jpg. Copyright ITV.
