For QR codes generated on the fly on another screen, that is obviously impossible. For QR codes on posters, I think the effort required to actually go about making stickers far outweighs any potential gain from hijacking a QR code.

Have you ever seen how many stickers for .com's still exist on post signs today? Imagine for every QR code for a movie poster someone slaps a link to their band's website. This would scale a lot better than their band's name with the .com, it would be cheaper to make, just as costly to distribute, less obtrusive, create more attention, and be way more deceptive.
