From Empire Online:

We spoke to our old pal, legendary horror film director George A. Romero, ooh, about an hour ago, ostensibly to talk about the upcoming DVD release of Land Of The Dead (out on Boxing Day, folks).

But what kind of movie news service would we be if we didn't take the time to ask him about his upcoming movies - and, to our surprise, the ever-affable Romero told us that a fifth Dead movie is very much on the cards.

"Now that Land of the Dead did so well in European markets and Japan, and the DVD is flying off shelves, there's talk of a sequel," he confirmed.

If it happens, a new Dead movie will follow the surviving characters from Land on their journey north, and as such will mark the first time Romero has made a direct sequel to one of his zombie flicks. And this time, there won't be a lengthy gap between films.

"Frankly, I was ok with that," because I'd much rather wait for something to happen, laughed Romero, referring to the political subtext that underpins each of his zombie movies. "If they nuke Washington, then I've got something. It won't be in April but it might now be August or something. I hope to God we don't have to do the winter again, but there's a real buzz happening now about a sequel."
