If you could be a character from a book or film, who would you be? Why?

The, Martian is the book I’m currently reading and the film was recently on TV.
I like it because the story by Andy Weir is more science based for a sci-fi film than fantasy. It depicts an astronaut who is abandoned on Mars after a freak accident. His colleagues assume he is dead and have to leave because their escape rocket is about to topple over which would trap them on Mars.
Why do I want to be the character in the film? I like the problem solving that has to happen to save the astronaut. He has to work out how to increase his food supply, chemically create water, travel across Mars and communicate with Earth after the communication system was destroyed. There are humourous episodes throughout the film, and tension increases as various mishaps occur. Not all the science is right but it is an enjoyable film. If I knew I was going to survive and come home I would do it.
