It's also possible for a catchphrase to hang around and enter common parlance even after its source has faded into the background to some degree.
For example: Headline writers still instinctively link "incredible" to "shrinking" as in "The Incredible Shrinking Candidate, "The Incredible Shrinking Economy," etc. But one has to wonder how familiar they are with the old 1956 movie or original novel by Richard Matheson?
And how many people remember these days that "Be afraid. Be very afraid." comes from the remake of THE FLY?
The Fly did not have a long lasting cultural effect, so that line losing its connection to the source in the memory of the population is not too surprising. I would say
The Incredible Shrinking Man is well remembered--perhaps still seen as THE entertainment example of "great and small" fantasy, so much so that it influenced everything from serious productions (Irwin Allen's
Land of the Giants) to parody (episodes of sitcoms such as
I Dream of Jeannie to films like
The Incredible Shrinking Woman, or
Honey, I Shrunk the Kids, etc.), and as you point out, "Incredible Shrinking" references of all kinds. Before the film, the general culture never thought to apply an overt or subconscious
fantastic implication to a situation; that film--in addition to its noted media influence--gave its larger than life (no pun intended) sci-fi spectacle to aid in the description of anything of a drastic nature, but I do not think it is completely divorced from the source in cultural memory.
As for whether Potter managed to resonate with multiple generations...everyone here knows exactly what we're speaking about when we say 'JK Rowling', don't they? Pretty certain you'd get a much smaller level of recognition of if you asked any non-Trekkie who Roddenberry was.
"Here"--if you mean this board--it is misleading, as this is TREKBBS, where fantasy productions are
the focus. That's not a mirror of the average numbers / members of the general population who are not all fans of HP, or were even aware that it was a book series. Moreover, you mention Rowling, but she is not the measure of a franchise's position in the culture--the creation is. If her
name recognition held that value, then I could easily argue that Mario Puzo's name was synonymous with
The Godfather as much as any character in his books, or the adapted versions from Coppola's films. Then again,
The Godfather films could be said to be as significant a franchise--if not more, if one considers the flood of memorable characters, plot situations, numerous quotes that became instant catchphrases. That, and its general recognition / association with real world culture and almost singlehandedly pushed the global popularization (right or wrong) of Italian-based organized crime, to the point where real life criminals complained about "misrepresentation" by the films, and an entire film sub genre's new boost as a result of the
Godfather films.
So there's no misunderstanding, gangster films existed since the dawn of cinema, but they were long out of vogue by 1972 (largely too "Hollywood" fake as in 1967's
The St Valentine's Day Massacre), and it cannot be denied that without
The Godfather, you do not get many of Scorsese's defining films, and in turn, you do not get Tarantino--and other filmmakers' endless fictional or adaptations of real gangster events. I challenge anyone to say
Potter had that kind of decades-long industry influence, as that brand of fantasy falls into the same category as LOTR (no matter the realm or time each are set in), and Jackson's films already redefined the fantasy genre in the 21st century.
, and probably has produced more merch than Trek managed in fifty years.
That sounds silly. TOS was already well merchandised while first run on NBC, but in its early 70s syndication boom
, the
"Star Trek Phenomenon" in merchandising took off, and was (like
Planet of the Apes) the model for every global franchise success to follow. Further, according to a 20
02 TIME magazine article, Paramount stated ST merchandise earned over
4 billion up to that time. With
14 additional years of earnings and innumerable items produced, ST's merchandise profile is not paralleled or surpassed by many.
