Besides her Tamil outing Kanchana 2 (2015), Taapsee Pannu has rarely found the opportunity to explore the supernatural thriller genre. While her next, Game Over, allows her to dive deep into the genre, she says that doing justice to her character - who suffers from anxiety and nyctophobia (fear of darkness) - did not come easy.

"The entire gamut of emotions - post traumatic stress, anniversary effect and the low self-confidence that a person experiences after a trauma - was new to me," begins Pannu, who plays a wheelchair-bound woman whose home has been broken into, in the Anurag Kashyap-presented thriller. To understand the psyche of the protagonist, the actor turned to the film's co-writer Kavya Ramkumar, whose family works with a Pondicherry-based NGO that helps people suffering from post-trauma stress disorders.
