Building full fledged models / generations of popular cities and places and leasing them to film producers. Its cheaper for them to lease than it would be to hire full devs and designers to start from scratch..I know there is some 're-use' in place by these companies such as pixar and disney. Re-use is not what i am talking about though. I am talking about movies like transformers / godzilla / etc which need on point rendering of actual cities and places.

Just a thought I had the other day when reading how film companies were struggling with growing movie budgets and diminishing returns.
