Of Agatha Christie and Hercule Poirot

I'm a big fan of Agatha Christie and love the series with David Suchet as Hercule Poirot. I've seen the role played with Peter Ustinov and Kenneth Branagh. Neither of them could hold a candle to David Suchet who played Poirot in every story Christie wrote about him. Over 25 years and thirteen seasons, David Suchet became the little Belgian detective with the moustaches. 

My husband and I just finished watching all of the seasons for about the fourth time. And then we watched the extras. Suchet answers a series of questions about what is essentially the role of his life. He described how he studied all the stories and kept a voluminous file about how Poirot dressed, ate, walked, spoke, etc. -- all that allowed David Suchet to disappear into the persona of Hercule Poirot, not an actor playing a character, but becoming one.
