Brad Pitt has revealed that he would be interested in a follow-up to World War Z.

The Hollywood A-lister has confirmed that he has had discussions about a potential sequel to the zombie action film.

World War Z has become Pitt's highest-grossing movie of all time, taking in over $500 million worldwide.

He said to Variety of a potential sequel: "We're certainly talking about it, yeah. We have so many ideas on the table from just the time we spent developing this thing and figuring out how zombie worlds work."

Pitt added: "We have so many ideas and so much information, we think we have a lot of stuff to mine from. We're going to do our best and see what we get out of it.

"We gotta get the script right first to determine if we go further."
