The high water mark for product placement in a Bond film (and maybe any movie) was Die Another Day.
A license to shill
With 20 marketing partners, Hollywood has never seen product placement like this
"Not only is MGM spending $30 million in advertising, according to Variety, the movie studio enlisted more than 20 marketing partners who are reportedly contributing at least $100 million in promotional support for the franchise.
Only the Olympics can boast more “official” sponsors."
Some of Spectre's promotional partners were listed in the press release that was distributed on the same day as the press event.
SPECTRE, The 24th James Bond Adventure, Set To Begin Production
"Promotional partners returning to the Bond franchise include Aston Martin, Bollinger, Heineken, Jaguar Land Rover, Omega, Sony Electronics, and Sony Mobile."
The Bond films receive direct payment from some companies, like Heineken, and additional promotional support from others, like Aston Martin. Aston Martin doesn't pay to have it's cars featured in the Bond films but will 'gift' or 'donate' cars to the production for on screen use. If the production needs 5 Aston Martins for a complicated chase sequence then they save a couple million dollars by not having to buy the cars.
With promotional support coming from private businesses, the Bond films also receive free marketing from the countries or regions in which filming takes place. This is less obvious than a slickly produced marketing campaign, but television and print news reports bolster a films presence in some key markets. Spectre is already prepping (and maybe shooting) key sequences in Austria. The press in that region have been all over it. Austria is in the heart of Europe and spill over markets for their reporting may be Germany, Hungary, Czech Republic, etc. Same thing goes for shooting in Italy. Same idea applies to the two Bond girls as well.
The production will save millions from tax breaks and promotional partners. That could drop the budget from, let's say, $320 Million to $290 Million. Sony and MGM are clearly unsatisfied with that number, though, considering Skyfall's success and what I know of Spectre's ambitious set pieces, I think the budget is well deserved and will be well spent.
