Romero could be quite grumbly about some of the work that followed in his wake - he was famously opposed to the concept of 'running zombies' explored in films like 28 Days Later... (2002) and the 2004 Dawn of the Dawn remake. He said last year that World War Z and The Walking Dead killed the zombie genre.
Then there were Romero's own latter-day zombie films, which began with 2005's Land of the Dead, and got progresively crummier after that.
But he didn't only make zombie films, and some of his other movies are classics in their own right. To mark the loss of this monster talent, I will run down his top five movies here.
All respect to The Crazies (1973), Martin (1978) and The Dark Half (1992), all three of which are also great.
George A. Romero's Top 5 movies
5. Monkey Shines (1988)
An underrated late-career winner from Romero, this concerned a paraplegic with a helper monkey who becomes murderous. They'd totally do it with CGI now.
4. Creepshow (1982)
Also hugely influential, this collaboration with Stephen King is an aesthetically-faithful big screen ode to EC Horror Comics. A notable antecedent to Sin City (2005).
3. Day of the Dead (1985)
The third film of Romero's original zombie trilogy takes place in an underground army bunker, a nightmarish location well-exploited by the filmmaker. Features the best death scene of all three classics ("Choke on it...").
2. Night of the Living Dead (1968)
The original black and white movie still packs a serious punch, but hasn't aged quite as well as...
1. Dawn of the Dead (1978)
Doubling down on the themes and scope of the low-budget original, Romero's sequel took the action to the mall and indicted consumer culture while chopping off the tops of zombie's heads with helicoptor blades. A stone cold horror classic with more on its mind than most 'serious' movies.
