Sony Pictures has contacted some US news outlets in an attempt to limit the damage caused by the hacking of its internal computer system last month.
The studio, its letter informed them, “does not consent to your possession… dissemination, publication… or making any use of the stolen information”.
Script details, salary data and private email correspondence have been leaked in the wake of the huge cyber attack.
A group calling itself Guardians of Peace has claimed responsibility.
It is believed that the attack was triggered by Sony’s new film The Interview, a comedy that features a plot to assassinate North Korea’s leader Kim Jong-un.
North Korea has denied being involved in the attack, but has described it as a “righteous deed” that may have been carried out by its “supporters and sympathisers”.
Variety, the New York Times and the Hollywood Reporter are among the publications understood to have been contacted by Sony’s legal team.
A New York Times spokeswoman said its coverage would “take into account both the significance of the news and the questions of how the information emerged”.
