Prabhas and Bollywood director Siddharth Anand have been in talks to make a film together for a while.
The project was first proposed by production company Mythri Movie Makers two years ago, but never came to fruition.
However, the company has now decided to give Siddharth Anand what he wants, effectively closing the deal.
Insiders say that the success of Shah Rukh Khan's "Pathaan" gave the production company confidence in Siddharth's ability to handle a big-budget film.
The film will star both Prabhas and Hrithik Roshan and is expected to be the most expensive in Indian cinema history.
Siddharth Anand will begin working on the script for the film after finishing production on his next film, "Fighter" starring Hrithik Roshan, with a projected launch date in 2024.
The combination of Prabhas, Siddharth Anand, and Hrithik Roshan is expected to generate a lot of hype at the box office and has the potential to break records.
