'Shaitaan' director Vikas Bahl said the ending of Gujarati film 'Vash' was "brutal and depressing" and he changed ending of 'Shaitaan' and made it positive as he didn't want to tell a story to people where "world is hopeless". "I don't want people to think black magic will win over our lives," he stated. 'Shaitaan' was inspired by 'Vash'.
