Brad Pitt has hinted that his upcoming movie 'World War Z' may become a franchise.
At the premier of the movie at New York's Times Square Monday, the 49-year-old actor said that the book of the same name from which the movie has been adopted has a lot of material and only a fraction of it could be incorporated in the movie, CBS News reported.
He added that if the people in charge want to do more, then there is a long way to go.
