Aryan Khan had a small role in Kabhi Khushi Kabhie Gham (2001) as the child version of Shah Rukh Khan’s character. He dubbed for the character Dash in Hum Hain Lajawaab, the Hindi version of the animated film The Incredibles, in 2004.

The Lion King centers on Simba, a lion cub who is driven out of his land by his evil uncle, Scar, and returns to claim his rightful legacy. Simba is fooled by Scar into thinking that he has murdered Mufasa, his father. 

The Lion King is the latest live-action version of a Disney animated film after The Jungle Book (2016), Dumbo (2019) and Aladdin (2019).
