Movies like Death on the Nile

If you want that specific blend of opulent confined settings, methodical Poirot-style deduction, and interconnected suspect networks, you're most likely to find it in Murder on the Orient Express (2017) or Glass Onion (2022)—both trap a sophisticated cast in claustrophobic luxury while a meticulous detective systematically dismantles their stories. The Death on the Nile formula of glamorous isolation plus escalating secrets probably also works with Evil Under the Sun (1982), though that's more familiar territory if you've already explored Branagh's Agatha Christie adaptations. Fair warning: most of these picks share the confined setting + detective unraveling motives structure, but few quite match Death on the Nile's particular visual lushness and pacing.
