In 1981–82, Amarapurkar acted in a Marathi stage play, "Hands-Up!", alongside stage actors Avinash Masurekar and Bhakti Barve-Inamdar. This play was successful and Amrapurkar was noticed by director Govind Nihalani, who was searching for an actor to play the central negative character in his movie "Ardh Satya". The movie went on to be a hit and Amrapurkar's acting was appreciated. His style of dialog delivery was considered unique as compared to the popular Hindi movie villains in those days. Amrapurkar won a Filmfare Award for his performance in the film.
