Rocky (1976) transformed from a low-budget project inspired by the 1975 Muhammad Ali-Chuck Wepner fight into an Academy Award-winning Best Picture, driven by Sylvester Stallone's refusal to sell the screenplay without starring in it. The film, best experienced in high definition to appreciate its gritty 1970s Philadelphia aesthetic and groundbreaking Steadicam work, remains an iconic underdog tale centered on character and resilience.
