hercule poirot movies

I have seen murder on the orient express and a haunting in venice movies starring the fictional detective herule poirot.And for both of them the plot and storyline is quite good and the themes that are explored are whodunit , suspense and mystery

All of these movies start with hercule being attached to the murder scene someohow and then hercule taking up on the case instinctively. What I like about these hercule movies is initiative to take and solve the case although definately its his duty to do but the epic scene is when 20 minutes are left and hercule calls all the people at the scene and faces them and reveal the murderer and explains in a chilling way as to how other people are involved or not involved in the plot. Since in these minutes we have to press back the arrow key multiple times to understand what he is actually trying to convey cause its this time duration only where the number of words he speaks in the minute actually doubles :)))
