The producers of the Bond movie have confirmed that an early script of the Sam Mendes-directed movie has been leaked online by the hackers, who have released tons of confidential data, including private emails of Sony bosses online.

Waltz said he was shaken by the cyber attack, reported People magazine.

"I would do everything differently, really," Waltz said at the premiere of 'Big Eyes'.

"I think it's very important to differentiate between the private sphere and the public one. If you invert that, you have nothing left anymore. Everything is public."
