Have tu notice that a book gets all famous after they make a movie out of it?

That's not at all how it works. Take for example any of those famous sagas like LOTR, HP, Twilight, The Hunger Games and many more, they all became huge hits when they were published. Millions of people bought those libros and they were translated in many languages, they became worldwide famous and THAT'S WHEN producers, screenwriters and directors decided to make cine out of it, because of all the success the libros had because if the libros are so popular, then the cine will surely make a lot of money too. After that, the book becomes even popular but it already was before they decided to make a movie put of it.

*cough* Twilight *cough
*cough* The Hunger Games *cough*
*Cough* Hitchhikers guide to the galaxy *cough*

Yeah.
It's because not too many people are enthusiastic about lectura books!!!
So when they see the movie, they see how cool the story/characters/whatever is, and most likely become encouraged to read the book.

I think that's a good thing, for the book.
I hate when people act like it's a bad thing??? They're like... wanna be hipsters o some shit? "Oh, tu didn't read the book before seeing the fucking movie, that makes tu not as good as us other fans!!! Hurr!!!" :/

yes! i really want this book (see in picture) as a movie but its like nobody has read it

Sometimes yes. What pisses me off the most is that sometimes I read a book I like it and wish it was made into a movie, but no one has read it and it is not popular at all, so there is no chance someone will make it into a movie :(
