This is what is currently driving pop culture; the commodification of the meme. Movies aspire to be memes - the dominant means of expression and the atomic unit of culture in the present moment.
They used to aspire to be themselves (movies, for their own sake). IMO that ended around 2008. The Dark Knight was the end and Iron Man was the beginning of a new Hollywood cycle; defined by the movie's ability to trade in this currency - memes - which stand alone, isolated, traded out of context of an entire narrative.
Further reading for whoever is interested: Society of the Spectacle by Debord (re: the degradation of being into having, having into mere appearing, as a universal and ubiquitous byproduct of the core function of capital which is commodification)... and Man and His Symbols (re: the difference between a symbol, which is universal and carries a wealth of meaning, and a sign, which is contextual/temporary and carries a fixed meaning).
