The film's use of cinematic techniques also plays a significant role in its lasting impact. Scorsese's innovative camera work, combined with the haunting score by Lalo Schifrin, creates a dreamlike atmosphere that immerses viewers in Travis's distorted reality. The iconic "You talkin' to me?" monologue, which has become a cultural reference point, is a testament to De Niro's captivating performance and Scorsese's direction.
