Return of the Living Dead: A Modest Proposal

After Night of the Living Dead, co-writers George Romero and John Russo eventually went their separate ways, and both continued different branches from the Night of the Living Dead tree.

Romero made his own series of sequels - Dawn of the Dead, Day of the Dead, Land of the Dead, Diary of the Dead, and Survival of the Dead. Russo wrote a novel, Return of the Living Dead, which he planned to adapt to film himself, although eventually, Dan O'Bannon wrote and directed The Return of the Living Dead.
