At an estimated cost of $200 million (£129 million), World War Z became the most expensive zombie film ever made when it was released this summer.

However, World War Z has gone on to make a tidy profit according to Paramount, who have reported that the film has grossed more than $500 million worldwide and made $305.2 million at the international box office to date, making it Brad Pitt's highest grossing movie after 2004's Troy, which made $497.3 million gross.

More remarkably, the film's success contradicts the negative press it attracted before its release in June. The movie, which is an adaptation of Max Brooks's 2006 bestseller World War Z: An Oral History of the Zombie War, had its release date put back and an extra $15-20 million spent on it to improve the original completed film. Fans were also troubled by news of script changes and Pitt's displeasure with the film's final state.

When World War Z was released, it received lukewarm reviews from critics, with Telegraph film critic Robbie Collin giving it two stars, but gained an aggregated reviews score of 67 per cent on Rotten Tomatoes.

World War Z compares favourably to the takings of this year's other blockbusters. Last week it was reported that Disney expects The Lone Ranger to lose $190 million (£124 million) after costing nearly $250 million (£161 million) to make, but taking less than $90 million ($58 million) at the US box office. Iron Man 3, while taking less than 2012's The Avengers, has grossed more than $1.2 billion (£775 million) worldwide. Despite successs in China, Guillermo del Toro's science fiction film Pacific Rim has failed to match the profits of World War Z, grossing $344 million (£222 million) worldwide.
