The Walking Dead was originally planned to be a tie-in to the classic zombie film by George A. Romero, Night of the Living Dead. Robert Kirkman’s iconic comic series is famous for reviving interest in zombies, particularly the slow-moving ghouls featured in George Romero’s original film. However, while The Walking Dead – by Kirkman and artists Tony Moore and Charlie Adlard – became famous for paying homage to Romero’s famous 1960s film, Kirkman originally planned for the series to be tied directly to the events of the movie.
