Vincent Kapoor works at NASA as Director of the Mars Mission.
In the movie he is an African-American man (Played by Chiwetel Ejiofor) who is one of the first of two people to realise Mark was alive directly after Mindy Park. He is the first person to establish contact with Mark Watney. His parents were Baptist
In the novel he is Venkat Kapoor and is a hindu man.Because of this change and also the change to Mindy Park Ridley Scott, the director, has been accused of being anti-asian and white washing the movie. I used to believe this until I read this article about what Andy Weir, the author, has to say on the matter.
