Back in 2020, actors Vicky Kaushal and Sara Ali Khan were all set to headline a big budget sci-fi drama titled 'The Immortal Ashwatthama' but unfortunately due to budget issues and the pandemic, the project was shelved. According to recent reports, the project has been revived and while Vicky is still a part of it, makers have decided to replace Sara Ali Khan. The buzz suggests that after revision of the script, makers decided that they needed an older actress to fit in the role.

A source close to the development told India Today, "After the film was indefinitely pushed and between revival, the script has been revised as well. While the earlier script demanded a young girl to be cast, Sara was on board. However, with the dates clashing and the change of role, it was no longer doable. The script in its current state needs a slightly older actress to be cast opposite Vicky. Hence, now the makers are looking at other options.” While actress Samantha Prabhu is rumored to be one of the front runners for the part, there is no official confirmation about her casting yet.

Talking about Vicky's casting, the source stated, “Today, it is the story that matters, not the stars. Vicky has a stronghold and credibility with the audience, so there is no doubt of him being recast. In fact, pre-production for the film has already begun. Since the film is mounted on a huge scale, the makers are spending nearly 8-10 months on pre-production to ensure everything is in place and ready.”
