'SPECTRE' represents ''unfinished business'' for director Sam Mendes.

The 49-year-old film-maker was responsible for the 2012 hit 'Skyfall', and having taken time off to reflect on the 23rd film in the Bond franchise, Sam concluded that he wanted to develop some of the characters he helped create.

Sam explained: ''I felt an attachment to the characters that we created in 'Skyfall'. I felt like there was unfinished business, and that there was a lot more I could do with them once I'd kind of stepped aside and had some time off.''

Speaking about the plot of the eagerly awaited new movie, Sam said he was looking forward to filming in a broader range of locations, which will include London, Rome, Mexico City, Tangier and Erfoud in Morocco, and Sölden, Obertilliach and Lake Altausee in Austria.

He told the BBC: ''A lot of the last movie was shot in and around London, which I loved, but there's a limited amount of stuff you can shoot in London, and I feel this has more mischief in it, perhaps, a little bit more of the unexpected.

''But it also does relate back to 'Skyfall' in many ways.''

At an event at Pinewood Studios in Buckinghamshire, South East England, earlier today (04.12.14), Sam announced 'SPECTRE' will be released on November 6, 2015.
