After Jerry McGuire, you heard the phrase "Show me the money." After
the Dalmatians, families bought Dalmations (and dumped them). After
Finding Nemo, kids flushed their fish down the drain. There must be
many more of those tidbits, real life consquences of fictional movies.
In language, behaviour, fashion, products. I'm looking for a book
filled with them (I couldn't find it), or for websites, or other
sources. I already have many quotes ("Phone home"), so I more
interested in the other forms.

The popularity of the movie "Top Gun" is said to have resulted in an
increase in military enlistments:

"...the career of naval aviation came to the forefront as a desirable
choice. While my casual Marine Corps contacts could not hazard any
guesses as to percentages, they confirmed my suspicion that the movie
had resulted in upsurges both in applications to the school and in
military enlistments overall, particularly in the Navy. Or at least,
at MCAS Miramar, "that's the rumor".

Thanks for the tips, pinkfreud! 
Maybe that book or website does'nt exist.

The effects of popular culture on social behavior forms the subject of
scholarly works, as well as, naturally, popular books. Search for
'popular culture" and "fads." A movie started the flagpole sitting
craze. The Yellow Kid put several phrases into the language. Lincoln
supposedly said, "So, you are the little lady who started the Civil
War," to the author of Uncle Tom's Cabin.
