The reason why publishing a book is the most difficult process is because the result is so unpredictable. Some books get rejected by dozens of publishers before making a big breakthrough in the literary world. It's easy for a publisher to look at Hop on Pop by Dr. Seuss and assume that he's on drugs and nobody would buy something so ridiculous, but obviously lots of kids ended up liking books like that. Sometimes the book is also adjusted to fit the taste of a potential audience, and sometimes it's not and that causes problems. The Interview is a great example of a movie that faced lots of issues with its audience. If that movie had been revised to some extent, the North Korean government wouldn't have flipped and threatened the US government over a movie that the US government did not endorse. It was withheld for the safety of our country, but people all over the world laugh at the idea of a comedy about killing Kim Jong Un, so the movie was high in demand. Would it have been as successful if the writers didn't knowingly infuriate a government that is already hostile towards us? I don't know, but the writers and producers ultimately decided that the film's success was more of a priority than keeping peace with North Korea. If you really want to watch the movie, you can watch it here!
