Every time - surely you have noticed- there are a greater number of literary adaptations in the world of cinema. In 2009 we could be talking about 25% of all released films coming from the literary world, in any of its facets.
In addition, all forecasts suggest that this percentage will be higher and higher.
Thus, great films such as "Slumdog Millionaire", "The Millennium Saga", "The Curious Case of Benjamin Button", "The Harry Potter Saga" and the Spanish "Cell 211" come from the literary world.
It should also be mentioned that all the superheroes that, in recent years, we are enjoying on the big screen, come from the world of comics, such as Superman, Spiderman, The Hulk, X-Men, The Fantastic 4, Iron Man and a multitude of new Marvel characters that are to come in the next few years.
It should also be mentioned that many writers, for several years, have generated their literary works thinking in frames, which also helps them to later sell well in the film market.
Long live literature and long live cinema.
