There are lots of films about writers, probably something to do with deadlines and writers block – you need to do what you know sometimes. Of course I don’t believe in the adage “Write what you know”, because I’ve never travelled in spaceship, or murdered anyone, (though judging from the films in the link, I just might not remember). I just prefer to write what I can imagine, and research the rest. Anyway that’s lucky – because otherwise I would be terrified of becoming a writer, if these represent what the screenwriters knew… http://www.flavorwire.com/367051/10-movies-that-make-writing-look-incredibly-dangerous/
