May be a longshot but - for however many IMAXes playing Hobbit in 15/70 (I know BFI IMAX London is definitely doing so, and possibly Lincoln Square NYC), attach an all-IMAX-footage teaser in front?
I promised myself not to watch any trailer, just the teaser. But if this first one is a trailer, I will not watch anything before the movie's released .
