The scientist thought that since the movie was based on a book by ex-wife Jane Hawking, it might be a biased portrayal of their relationship.
"I was rather surprised that a major film company should want to make a film about me. At first, I was worried because it was based on a book by my ex-wife, Jane, but I was reassured when I read the script, and even more when I saw a first cut of the film," Hawking, who turned 73 recently, said, according to Universal Pictures India.
The movie releases in Indian theaters on January 16, 2014.
