When their ocean liner capsizes, a group of passengers struggle to survive and escape.
The Poseidon Adventure is the definitive disaster film of the 1970s and essentially invented the modern disaster movie template. Its novelty score is high because it established a genre formula that dozens of films tried to replicate — the upside-down ship concept was genuinely inventive and visually striking for its time. The plot is competent genre fare, following a diverse group of survivors through escalating set-pieces, though it relies heavily on archetypes. The acting is a mixed bag — Gene Hackman and Ernest Borgnine bring real energy and conflict, but several supporting performances are broad and melodramatic. Cinematography is serviceable and occasionally impressive given the practical challenges of filming in an inverted set, but not artistically distinguished. The ending delivers emotional punch with its sacrifice theme but doesn't fully transcend its genre constraints.
