Horror comedies are thriving at the box office, with Shraddha Kapoor and Rajkummar Rao’s “Stree 2” recently achieving significant success. Anticipation builds for “Bhool Bhulaiyaa 3,” releasing for Diwali, following a mixed reaction to its teaser. The trailer will drop on October 6, and if it meets expectations, the film, featuring Kartik Aaryan and Triptii Dimri, could have a strong opening.
