I've read the novel by Paula Hawkins and it's a personal favourite. The characters are layered, full of intrigue, and have potential for multiple interpretations.
Some of the reasons why I am looking forward to it --
1. Parineeti's comeback vehicle - I've always rooted for Parineeti and find her a gifted actor. This might be her chance to get back into the game.
2. Avinash Tiwary in a mainstream BW movie - Love this guy, he's so talented. This might be his chance to get noticed by the who's who of Bollywood.
3. Kirti Kulhari and Aditi Rao Hydari in supporting roles - Kirti especially has great acting chops.
Here is the trailer of the original film for those who've missed out on it --
