While Anil has lent his voice for Karna, Manoj has dubbed for Yudishtir's character in the animated story.
The actors were spotted at the Future Works Studio in Andheri recently and the film's producer Jayantilal Gada confirmed their addition to the cast.
"Both Anil and Manoj have shown full commitment. It was very gracious on their part to agree to impart voices to two very important characters in my film," Gada said in a statement.
Anil took 15 days to complete his work, but Manoj finished the dubbing for his character in just four days.
