I want to watch the film but it's the first time I hear about a book... So the Actually, it makes the impression as if they made the movie fully aware they’re making it for the book’s fans, and decided that everyone who’s going to watch it have read the book anyway. part worries me a little.

On the other hand, speaking of looks, can someone kindly explain me why orange is apparently the bestest color for suits on Mars…?
In terms of movies... Because the Martians are supossed to be green so orange suits make a nice contrast? ;)
