Hackers stole a copy of the script for the latest James Bond movie, Spectre, in a cyber attack on Sony Pictures.
The film's producers discovered the loss on Saturday.
Spectre is due for release on November 6.
Filming began this month after producer Barbara Broccoli and director Sam Mendes unveiled the title, cast and new Bond car, but little about the plot.
Cyber security specialists said the attack would cost Sony Pictures about $100-million to put right.
A Sony spokesman said news reports that the attack had forced the studio to stop production on films, including Spectre, were wrong.
"Productions are still moving forward," said Robert Lawson.
The theft of the script is not the first setback for the new Bond film - nine customised cars especially built for it were stolen from a garage near Dusseldorf, Germany, reports said last week.
According to The New York Times, the cars, including five Range Rover Sport SUVs, were to be shipped to the Alps, where filming is expected to begin next week.
Hackers launched an attack on Sony last month, disabling its computer network and stealing and leaking a trove of sensitive information in the most severe cyber attack on a company in the US.
The hackers' identity has yet to be confirmed, but it is believed that Guardians of Peace, a hacking collective suspected of having links with North Korea, is behind the attack, which took most of Sony Pictures' computers offline.
North Korea has been linked to the hack because Sony's forthcoming film The Interview is about a CIA plot to kill Kim Jong-un, the dictatorship's supreme leader.
