The hackers who attacked Sony's computer network in November made off with the new James Bond film script.
The film's producer, Eon Productions, said an early version of the script was taken, according to a statement on its website.
They're worried the hackers will publish the script online, potentially spilling Spectre's secrets to millions of fans ahead of its release date in November 2015.
Eon Productions said on its website:
Eon Productions, the producers of the James Bond films, learned this morning that an early version of the screenplay for the new Bond film Spectre is among the material stolen and illegally made public by hackers who infiltrated the Sony Pictures Entertainment computer system.
Eon Productions is concerned that third parties who have received the stolen screenplay may seek to publish it or its contents. The screenplay for Spectre is the confidential information of Metro-Goldwyn-Mayer Studios and Danjaq, LLC, and is protected by the laws of copyright in the United Kingdom and around the world.
It may not (in whole or in part) be published, reproduced, disseminated or otherwise utilised by anyone who obtains a copy of it. Metro-Goldwyn-Mayer Studios and Danjaq LLC will take all necessary steps to protect their rights against the persons who stole the screenplay, and against anyone who makes infringing uses of it or attempts to take commercial advantage of confidential property it knows to be stolen.
In Spectre, which is the 24th official James Bond film, a cryptic message from Bond's past will send him on the hung for a sinister organisation.
A Sony spokesman told Reuters that filming, which began this month, has not been affected by the cyber attack. They said the productions were still moving forward.
