The script I'm working on currently is a roadtrip movie, and the travelers will munch on burgers & cookies, drink soda & lemonade at various points; if I can get someone to pay me some money (or feed the cast and crew for a day or 2?) in exchange for having their product in there, I'd be thrilled.
That's a lot different than a completely extraneous ECU of the Armalite logo on a soldier's rifle - specifically the logo stamped into the lower, not a reaction shot of the soldier, a special just for the logo. There's a question of emphasis here. Is the PP incidental to the scene, seamless, or does it call attention to itself like the shot I just mentioned from WWZ.
