While the fourth movie in the $490m Poirot franchise is expected, it hasn't actually been greenlit just yet. However, since the only obstacle seems to be whether Kenneth Branagh wants to continue (he's given no indication that he doesn't) the next Poirot movie after A Haunting in Venice could be confirmed soon.

upward-curled In The ABC Murders, Poirot reveals that he frequently visits an expensive hairdresser and in Murder on the Orient Express we learn that he uses a little pair of curling tongs on his moustache to give it the 'upward-curled' shape.

He has also been depicted in film and television by an array of actors, with Kenneth Branagh's latest iteration, A Haunting in Venice, opening on the big screen in September 2023. Poirot's characteristics have led us to speculate that he may be autistic, even though Christie never explicitly said so.

A Haunting in Venice A Haunting in Venice's box office has now surpassed $100 million, but the film has fallen short of the previous two entries in the franchise. The new sequel is on track to be the lowest-earner of the three Hercule Poirot movies, casting doubt on the Agatha Christie franchise's future.

For sure echoes of the past are a far cry from a World War I flashback that informs us that the famous detective once had a fiancee (what happened to her anyway?) and that battle scars (and his now missing fiancee's advice) led him to grow his famous moustaches.

Hercule Poirot He was injured in battle and his love interest was killed in a train bombing. Heck, even Poirot's glorious mustache gets a tragic origin story: He grew it to cover up his scars.

Watson (Captain Hastings) in tow, Poirot was quickly established as the classic eccentric private detective. Interested mainly in solving cases, though with a taste for the finer things in life, Poirot spent 32 novels and 49 short stories as an asexual hero with no love interest or love life whatsoever.

Countess Vera Rossakoff is the only woman to whom Hercule Poirot has ever admitted being attracted. The countess' true name is a mystery.

The new Poirot film sees Kenneth Branagh return as the classic detective for a third time, following his portrayal in Murder on the Orient Express and Death on the Nile.

Poirot's characteristics have led us to speculate that he may be autistic, even though Christie never explicitly said so.

The final shot of the film sees Poirot listening to Salome sing the blues in a nightclub, having finally shaved his mustache to reveal his scars.

The moustache represents freedom, both to Mike and his grandmother, but in vastly different ways. For Mike, the moustache is a symbol of his freedom in rebellion.
