Amitabh became Taapsee's reference point for her role, which sees her seeking justice for a client she believes is being framed owing to his religion.
"Bachchan Sir's character in 'Pink' was the best point of reference for me. Since I have worked with him in the film, I watched him closely and learned how he executed the role," Taapsee said in a statement.
"While we are diverse as actors, and the situation my character is in, is different, there were specifics that I picked up from watching him personally. His sternness and conviction is something that I took observed closely. He could build the personification that the character needed. His dedication to his craft, his discipline, and his focus are commendable," she added.
