When did Hollywood become really liberal?

Look at the villains in movies.  Without fail they are either "evil businessmen" or "evil corporations."  In the rare event one has a public sector villain, it is revealed in the "shocking twist" that the government is in fact doing the bidding of some evil corporation.  In the incredibly rare event that the villain is the government alone, the filmmakers are sure to show that it is controlled by straw conservatives.  When the villain is "terrorists" etc. they tend to be neo-Nazis or the like (they are sure to be shown making some racist or sexist comment to prove their Evilness), or if they appear to be fighting for a leftist cause it is unfailingly revealed in a Shocking Twist that they are in fact being controlled by an Evil Corporation.

If you do polls of the American public, there's a lot more hostility to government than to business.  The former is much more obvious to produce a murderous conspiracy in the first place - there are dozens of examples of governments conducting secret illegal plots that would produce exciting movies, but not too many of "evil corporations" (who have limited resources, have to pay attention to profitability, have to report their income to tax agencies, and are held accountable for their actions).  Popular conspiracy theories almost always involve the government and very rarely involve "evil corporations" (if they do, typically banks, rarely depicted as film villains).

Even if we say that, regardless of realism, if Hollywood were centrist it would have an equal number of "liberal" villains (evil corporations, evil businessmen, neo-Nazis, etc.), and "conservative" villains (the government, Islamic terrorists, leftist terrorists), it doesn't hold up.  The former occur more than the latter by a ratio of about 10-1 or so.
