20 Things You Didn't Know About American Psycho

19. The $7 Million Budget Mostly Consisted Of Music Licensing Costs

The film ended up costing a rather svelte $7 million, undeniably aided by the fact that Christian Bale was an up-and-comer incapable of commanding a massive salary.

As it turned out, the bulk of the budget was a result of the film's extensive use of pop music, including the likes of New Order, Genesis, Robert Palmer, Depeche Mode, Huey Lewis and the News, Chris de Burgh, and Simply Red.

Given the notorious expense involved with licensing hit songs, it's honestly pretty impressive that they could score so many pop classics while bringing the entire budget well under $7 million - especially with name actors like Willem Dafoe and an on-the-rise Reese Witherspoon.
