Is anybody aware of the fashion designer/clothing brand 'Tom Ford'? His stuff is about as high a quality you can get and extremely expensive (suits start at around €5,000, knitwear is around $1,000 and shirts start at ~$400). Almost every garment in the last Bond movie (
Quantum of Solace was by Tom Ford, and despite the fact that you don't see a single Tom Ford label or hear the brand mentioned once in the entire movie, sales of Tom Ford clothing shot up after it's release.
I find this kind of approach interesting - instead of having Tom Cruise on his iPhone while hanging from skyscraqers and shooting bad guys, having the 'products' placed within the movie but without any obvious branding, and instead only drawing attention to it in the marketing campaign. I think it works quite a bit better - the fact that all of Bond's suits are by Tom Ford is great for Tom Ford, but the average Joe that has no interest in dropping $5,000+ on a suit won't have his immersion broken by endless logo-dropping during the movie.
