Sony has accused Disney of “irregularities” in its claims for Pirates of the Caribbean 3s opening-week box office performance.

The movie house has called into question its rivals claims to have set a new record in its first six days release on the world box office.

Disney said it had made $251 million £126.9 million outside North America and $404 million £204.4 million overall.

However, Steve Elzer, corporate communications chief at Sony, rejected the claim in an unusual release to the media.
