Although Matt Damon is much loved by all I feel That the book portrays a slightly different look on the characters. Read on to find out who i think should play The cast.
The Chicago Fire Star has the right build to be able to play the Role of Mark Watney. I think that for the role he would have been able to play the hardships of being stranded much better than Matt Damon.
For the Role of Melissa Lewis. Bryce Dallas Howard would have been a better choice. Her role in Jurassic World made her acting career sore through the roof. The Book portrays Melissa as a kind and caring person, I think that she would have been able to portray that better than Jessica Chaistain (Interstellar).
The film comes out October 2nd 2015.
