This Is Why Amitabh Bachchan Refused To Work With Kareena Kapoor Khan!!

For Black, Bhansali had two extreme choices regarding casting: either cast Kareena Kapoor Khan and leave Amitabh Bachchan out, or the other way around.

 
The path of Sanjay Leela Bhansali and Kareena Kapoor Khan have intersected in a mysterious way. Every time they've gone too close to work on a movie together, things have ended badly. Bhansali's approach to Bebo for Hum Dil De Chuke Sanam, followed by Devdas and Black. We'll take a long break at Black since a lot transpired during the casting process, but she was also approached for Ram Leela.
Kareena has always amazed Bhansali, who attempted casting her several times before they found a suitable role for Black and everything fell into place according to their respective temperaments. However, Kareena's potential career-defining job quickly disappeared from her peripheral!
It has been said that Amitabh Bachchan refused to accept the film's offer after learning that Kareena Kapoor Khan would be playing the major part of Michelle. Bachchan decided quickly that he would not be working on a project with Kareena Kapoor Khan since he was in the mood to boycott the Kapoor family.
It was hardly surprising what came next. Nothing in the world could convince Bhansali to disagree with Amitabh Bachchan's casting of Debraj Saha, which he had written for him. Kareena Kapoor Khan was instantly fired from the movie by him. And why had Amitabh Bachchan made such a strong demand? It was an additional request.
A purported demand made by Babita following Abhishek Bachchan's engagement to Karisma Kapoor. The Bachchans were displeased with the demand made by Karisma and Kareena's mother, therefore they refused to comply and the much-discussed engagement was called off. Amitabh Bachchan made the decision to never again collaborate with the Kapoors as a result.
Over time, though, circumstances between the two families shifted since Shweta Bachchan Nanda, the daughter of Amitabh Bachchan, was already wed to Nikhil Nanda, the son of Ritu Nanda, the mother of Karisma Kapoor.
Many years later, Kareena Kapoor Khan and Amitabh Bachchan collaborated in Satyagraha. After conducting some research, we came into a Reddit thread that covered similar dynamics. In actuality, Amitabh Bachchan's firm stance also startled Redditors! In response, a commenter said, "Back then, Bebo also lamented in KWK that she was left to bear the burden of her sister's breakup because she was no longer able to work with Abhishek. The Bachchans are resentful. While Bebo went on to become a successful actress and is still going strong, AB's son is now a has-been. 
The previous year, on October 11, amid the festivities honouring Amitabh Bachchan's60th birthday, Abhishek Bachchan and Karisma announced their engagement. However, the engagement was called off shortly after.
