The Fox Licensing page is nowhere in sight, unless it is part of the FOX Network site.
But this is the FAQ page for licensing Universal clips and stills.
I am considering a Furious 7 license for my next VP project. I can buy this online at the Universal site, but haven't a clue about FOX.
And there may be additional steps with physical merchandise, such as final studio approval, etc. Be very afraid...
Please see "When do I need to purchase a license for clips?"

EDIT: For 20th Century Fox licensing info, I guess you or I would need to do a Custom Request at this page.
Other wise, Excuse Me!

That page is part of their jobs and services site, for props, workmen, etc.
I wonder if they need a Fart Foley? If "Yes", then I'm their Man! Expert.
Else, that "Predator Guy" beat me to it.
