Going to watch The Martian again. Because.
@bigzaphod So good. Book is better and audio book narrated by RC Bray (no longer available) is superb.
My fellow saw the movie first, then I let him listen to my audio book, and a one point, he came into my office with a stricken look on his face. "How did they leave this out of the movie?" He did that a few more times. :)
Of course, a movie only has so much space, and the screen writer(s) did an amazing job.

@bigzaphod I’m sorry, what was your name again?
I’m Teddy. The director of NASA.
Andy Weir has such an amazing sense of humour that was well-conveyed in the movie. Looking forward to Hail Mary.
