Jude Law is taking legal action against The Sun newspaper, claiming the Rupert Murdoch-owned tabloid hacked into voice mails for stories about his private life.
Murdoch's News International strongly denies the claim, accusing the actor of "a deeply cynical and deliberately mischievous attempt" to drag The Sun into the hacking scandal that has brought down its sister paper, the News of the World.
In a statement Friday, News International said Law's allegations "have no foundation whatsoever" and vowed to vigorously fight his claim.
Law's law firm, Atkins Thomson, declined to give details of the claim, which it said "will be considered by the court in due course."
Law is also suing the News of the World. That case is due to be heard next year.
