Zombie movie maestro George A. Romero has died at age 77, the Los Angeles Times and Variety are reporting.

The writer/director is known for his Night of the Living Dead franchise.

Since releasing his small-budget 1968 film Night of the Living Dead, Romero has put out plenty of zombie films, including Dawn of the Dead (1978), Day of the Dead (1985) and Land of the Dead (2005). His work has inspired a number of present-day filmmakers, many of whom took to Twitter to tweet their condolences.
