Brad Pitt and director Marc Forster hit the red carpet last night for the Moscow premiere of World War Z, debuting in theaters tomorrow. When asked about a possible sequel to this adaptation of Max Brooks' zombie novel, the actor revealed there is plenty more material from that book which could be used in future movies.

"There is enough to mine from the book. We could barely get a fraction of the book in. So we'll see. We'll see."

Director Marc Forster revealed he would be interested in a sequel, provided this movie fares well at the box office.

"Let's see how this goes. We hope this movie goes well and we shall go from there."

Back in January, we reported that both Paramount Pictures and Marc Forster viewed World War Z as the start of a trilogy. We haven't heard any official movement on a follow-up yet, but if this zombie thriller does well at the box office, don't be surprised to here more on a sequel soon.
