George Romero, whose classic Night of the Living Dead and other horror films turned zombie movies into social commentaries and who saw his flesh-devouring undead spawn countless imitators, remakes and homages, has died. He was 77.

Romero died Sunday following a battle with lung cancer, his family said in a statement provided by his manager Chris Roe. Romeroโ€™s family said he died while listening to the score of The Quiet Man, one of his favorite films, with his wife, Suzanne Desrocher, and daughter, Tina Romero, by his side.

Romero is credited with reinventing the movie zombie with his directorial debut, the 1968 cult classic, โ€œNight of the Living Dead.โ€ The movie set the rules imitators lived by: Zombies move slowly, lust for human flesh and can be killed only when shot in the head. If a zombie bites a human, the person dies and returns as a zombie.

Romeroโ€™s zombies, however, were always more than mere cannibals. They were metaphors for conformity, racism, mall culture, militarism, class differences and other social ills.

โ€œThe zombies, they could be anything,โ€ Romero told the Associated Press in 2008. โ€œThey could be an avalanche, they could be a hurricane. Itโ€™s a disaster out there. The stories are about how people fail to respond in the proper way. They fail to address it. They keep trying to stick where they are, instead of recognizing maybe this is too big for us to try to maintain. Thatโ€™s the part of it that Iโ€™ve always enjoyed.โ€

Night of the Living Dead, made for about $100,000, featured flesh-hungry ghouls trying to feast on humans holed up in a Pennsylvania house. In 1999, the Library of Congress inducted the black-and-white masterpiece into the National Registry of Films.

Romeroโ€™s death was immediately felt across a wide spectrum of horror fans and filmmakers. Stephen King, whose The Dark Half was adapted by Romero, called him his favorite collaborator and said, โ€œThere will never be another like you.โ€ Guillermo del Toro called the loss โ€œenormous.โ€

Romeroโ€™s influence could be seen across decades of American movies, from John Carpenter to Edgar Wright to Jordan Peele, the Get Out filmmaker. Many considered โ€œNight of the Living Deadโ€ to be a critique on racism in America. The sole black character survives the zombies, but he is fatally shot by rescuers. Peele on Sunday tweeted a photo of that character, played by Duane Jones, and wrote: โ€œRomero started it.โ€

Ten years after Night of the Living Dead, Romero made Dawn of the Dead, where human survivors take refuge from the undead in a shopping mall and then turn on each other as the zombies stumble around the shopping complex.

Film critic Roger Ebert called it โ€œone of the best horror films ever made โ€“ and, as an inescapable result, one of the most horrifying. It is gruesome, sickening, disgusting, violent, brutal and appalling. It is also … brilliantly crafted, funny, droll, and savagely merciless in its satiric view of the American consumer society.โ€
