Hollywood studio Sony has accused Walt Disney Pictures of over-exaggerating sales of the latest Pirates Of The Caribbean movie. Sony claims box office figures for Pirates Of The Caribbean: At World's End included a seventh day instead of the usual six. The third installment of the swashbuckling series grossed $401 million (GBP200.5 million), but Sony - the company behind Spider-Man 3 - claims that with a seventh day taken into account, Spider-Man outperformed the Pirates sequel with $418 million (GBP209 million). Walt Disney Pictures admitted they included figures for worldwide previews in the total, but insisted this contribution to the final figure was minimal.
