Who made Cab Driver a hit?

While several factors contributed to *Taxi Driver*'s success, Martin Scorsese's direction is widely considered the most crucial element in making it a hit. His distinctive style, combined with the strong performances from Robert De Niro and the compelling script by Paul Schrader, created a film that resonated with audiences and critics alike. The film's impact also benefited from strong marketing and distribution by Columbia Pictures. In short, it was a collaborative effort, but Scorsese's vision is largely credited with its success.
