'SPECTRE' is already over budget by around $50 million.

Leaked documents from the recent cyber attack on Sony have revealed some of the financial details of the much-anticipated new James Bond film, showing that the budget was originally ''in the mid $300 millions'', but has been reduced to $250 million by the studio.

In a series of emails sent by MGM president Jonathan Glickman, he says: ''We recognise that this movie needs to build on the past few films - and there are expectations we must meet for the audience. Still, we must find further cuts.

''This is not about 'nickel and diming' the production.''

Barbara Broccoli, the producer, responded angrily to the messages.

What's more, a leaked email from Sony's Amy Pascal revealed her disappointment over 'SPECTRE'.

She wrote: ''It's insane and you know with no script this movie is gonna go over budget.''

The emails also reveal 'SPECTRE' director Sam Mendes was keen to secure the services of 'Sherlock' star Andrew Scott for the role of Denbigh in the film.

Chiwetel Ejiofor from '12 Years a Slave' was initially cast in the role, but it was decided his salary demands were too high.
