The actress will take on the role of a journalist in Prakash Jha's Satyagraha.
A source told the Hindustan Times: "She is doing really intense research for this role. Her part in the film is difficult and she wants to make sure she does complete justice to it.
"Kareena has asked for videos of the major stories reported by Christiane. She has also asked for documentaries based on her and all the interviews she has done along with videos of her being interviewed.
"Since she's taking inspiration from such a renowned reporter, she doesn't want to mess it up in any way."
Kapoor has confirmed she has taken on the drama film.
The actress recently said that she has no interest in going on to direct films herself.
She will next be seen performing an item number in Dabangg 2.
