Sunny Kaushal watched Ted Bundy and Jeffrey Dahmer interviews for his role as Abhimanyu in "Phir Aayi Hasseen Dillruba."

He observed that both killers believed their actions were justified, a mindset mirrored in his character.

Abhimanyu, a kind but twisted man, competes with Rishabh for Rani's affection in the Netflix sequel.

Kaushal found it essential to create his own interpretation beyond what he learned from the serial killers.

The film, directed by Jayprad Desai and written by Kanika Dhillon, is streaming on Netflix from August 9, 2024.
