Evil Under The Sun (1982, dir. Guy Hamilton)

Investigating a stolen jewel, Poirot finds himself at a luxury resort where there is murder afoot. An if-it-ain’t-broke sequel to Death On The Nile, though this time with the camp dialled right up. Solid cast, a fancy isolated location, a puzzle to solve, no-one taking things too seriously.

Here’s the trailer.

Murder on the Orient Express (1974, dir. Sidney Lumet)

Hercule Poirot must investigate a killing on a luxury sleeper service. Handsome if slightly stagey and camp version of the Agatha Christie stalwart. An awkward backstory and too many starry suspects make for tricky telescoping of the novel, but fans won’t mind a bit.

Here’s the trailer. And a previous review.

Knives Out (2019, dir. Rian Johnson)

A famed mystery writer is killed; an unconventional detective arrives. Sharp, witty and well-constructed comedy-thriller, a love letter to Agatha Christie and to the likes of Deathtrap and Sleuth. Bags of fun, with a game cast of character actors all enjoying themselves. Recommended.

Death on the Nile (1978, dir. John Guillermin)

Hercule Poirot holidays in Egypt; murder is soon afoot. Quasi-sequel to Murder on the Orient Express. Breezy escapist fun with a rich cast of character actors and bright young things hamming/preening respectively, though its clumsy treatment of non-whites plays as racist rather than as innocent comic relief.

Murder on the Orient Express (1974, dir. Sidney Lumet)

Hercule Poirot finds himself in the middle of an elaborate onboard murder. Classy all-star version of the Agatha Christie warhorse. The business of the plot makes in-depth characterisation problematic, but everyone gets their moment to shine, with no resorting to the opening out of the recent Branagh version.
