Sony has complained of "irregularities" in Walt Disney's boast that its latest Pirates of the Caribbean movie has smashed box office records.
In a rare public spat between the two Hollywood studios, Sony has accused Disney of including a seventh day of takings in figures purporting to show unprecedented six-day takings of $401m (£202m) for the third part of the series, At World's End.
Previews in several countries were rolled in to the total, though Disney said this did not amount to many filmgoers. Sony said that including a seventh day, its recent hit Spiderman 3 grossed $418m.
