He moved to Mumbai, where he initially started working as an engineer[3] but quit his job to begin his acting career.
[4] Due to his somewhat intimidating appearance, caused by a tumor near his pituitary gland, Agarwal starred in Hindi films and television as demonic/ghostly characters or villains in general.
He also featured in two Hollywood films; playing a supporting antagonist in Stephen Sommers' 1994 live action adaptation of The Jungle Book and later briefly appearing in Such a Long Journey.
And in 1994, when he was approached by Shekhar Kapur for the role of Babu Gujjar in Bandit Queen, it was a defining moment as he got the right opportunity to demonstrate his versatility as an artist.
He later joined hands with his friends Aamir Khan for Mela in 2000 and with Akshay Kumar for Talash: The Hunt Begins in 2003.
