It is a widely known item of cinematic lore that Paul Schrader's screenplay for "Taxi Driver" was inspired by " The Searchers ," John Ford's 1956 film.
It was the most cinephilic movie ever made in Hollywood, openly acknowledging Bresson, Hitchcock, Godard, avant-gardists Michael Snow and Kenneth Anger, and the John Ford of The Searchers.
It's at the center of Martin Scorsese's “ Taxi Driver ,” written by Paul Schrader , who used it again in his own “Hard Core.”
Haunted by John Ford’s The Searchers (1956) and the tormented racist Ethan Edwards’s redemptive quest to rescue his teenage niece from miscegenation with a Comanche chief, Schrader first updated it in Hardcore (1978), about a Dutch Calvinist furniture manufacturer wresting his daughter from LA pornographers, then used it as the basis for Taxi Driver.
With Travis’s streaks of implied racism, less hateful than incidental, and attempted chivalry, the film is indebted to John Ford’s The Searchers , but Travis’s misanthropic anger is a decidedly modern beast born of neon lights and the demons of a post-Vietnam culture.
