I've only done some work on (the screenplay), and I find it very difficult, actually. Because you can really get away with murder in a book. You write 'round so many things, you can describe people, you can explain things. A screenplay is actually very short. It is only, like, 110 pages long and it's very spread out and every line has to do so many jobs, so I found it really hard.
