The horror genre was a late-blooming genre in Indian cinema. Regionally, there were some horror films made before the 70s, especially in Malayalam cinema, but Bollywood has lagged behind this trend, except for a few psychological thrillers disguised as horror. It was Ramsays who started the craze here and hasn’t looked back since. Over the past 20 years, Bollywood horror movies have also started making money at the box office courtesy of Vikram Bhatt and Ram Gopal Varma. But the highest-grossing Bollywood horror movies will surprise you. There have been blockbusters in the horror genre such as Raaz, Bhoot, 1920, Stree, Bhool Bhulaiyaa, Haunted, and so on.
