Amitabh Bachchan and Rishi Kapoor reunite on screen

Amitabh Bachchan and Rishi Kapoor will reunite on screen for Sudhir Mishra's directorial venture Mehrunnisa.

The actors were last seen together on screen 28 years ago in Manmohan Desai's Coolie.

A source told The Times of India: "It is a script that Sudhir Mishra started writing in 1996. However, it failed to take off that time. Saurabh Shukla is writing the dialogues for the film."

The project, produced by Nikhil Advani, will also feature both actors' sons - Abhishek Bachchan and Ranbir Kapoor - who make cameo appearances.

While Amitabh and Abhishek have worked together in films such as Bunty Aur Babli, Sarkar and Sarkar Raj, Rishi and his son Ranbir have never appeared together on screen.

Describing the storyline, the source said, "The film starts off with two old men played by Amitabh Bachchan and Rishi Kapoor reminiscing about their past. Here is where Abhishek and Ranbir come in. They play their respective fathers' younger selves.

"Nikhil wanted to take this film on the floors this year. But both Ranbir and Abhishek are busy with other projects now. The film will go on floors only next year now.

"Neither Nikhil nor Sudhir want to talk about the project right now. It's a huge project and they want to announce it in a big way later. Both Amitabh and Rishi have loved the script and agreed to do it. In fact, the film should also star Sudhir's favourite - Chitrangada Singh."

Amitabh Bachchan and Rishi Kapoor have starred together in several films including Amar, Akbar, Anthony, Naseeb and Kabhie Kabhi.
