#5: His Collaboration With Martin Scorsese On Mean Streets Launches Him Into Stardom
De Niro’s meeting with director Martin Scorsese in the early 1970s became one of cinema’s most iconic partnerships. Their first major collaboration, Mean Streets (1973), transformed both of their careers. De Niro’s volatile performance as Johnny Boy captured the spirit of gritty, urban America with raw authenticity.

The film premiered to critical acclaim and instantly established De Niro as a new kind of leading man — unpredictable, dangerous, yet deeply human. His chemistry with Harvey Keitel and Scorsese’s streetwise direction created a new realism in American cinema that shaped the decade’s tone and De Niro’s trajectory toward stardom.
