Bachchan, who is currently shooting his upcoming film 'Piku' in Kolkata, said the actor was close to his heart.
"Waking up in Kolkata to the sad news of the passing away of Sadasiv Amrapurkar.. A colleague and a gifted talent.. Prayers! When a colleague suddenly passes away there is a sudden vacuum, of times spent together, of acknowledgment of their work..," Bachchan posted on Twitter.
Amrapurkar, 64, died here on Monday morning due to lung infection.
Filmmaker Madhur Bhandarkar recalled his experience with Amrapurkar in his debut film 'Trishakti' in 1999.

"Saddened to hear about the demise of #SadashivAmrapurkar. An effortless actor, Sadashivji had his own style and always brought something unique to the table. We have lost a genuine human being. RIP," Bhandarkar tweeted.
Kher, who shared screen space with the late actor in 1993 film 'Meherbaan', said, "I am so saddened to know about the demise of a fine human being and a wonderful actor Sadashiv Amrapurkar. He was a kind and a learned man. RIP."
Mahesh Bhatt, who gave him one of the finest roles of his career in 'Sadak', said, "I had heard that he was keeping well from quite a sometime. But his was a sudden end. I remember him very fondly. He contributed to my blockbuster 'Sadak' in a very big way... He was a solid rooted person and had a clean political ideology."
Director Kunal Kohli remembers the actor for portrayal of a ruthless eunuch in 'Sadak'.
"#SadashivAmrapurkar's portrayal of #Maharani in #Sadak rates as one of the best by a villain ever in Hindi cinema RIP."
Funnyman Raajpal Yadav said, "The end of rustic cinematic era as we mourn the death of multifaceted actor and a compassionate #human being Mr #SadashivAmrapurkar."
Actor-turned-filmmaker Pooja Bhatt said he was the one of the most 'relevant' villain after Amjad Khan's powerful portrayal of Gabbar Singh ('Sholay').
"Sadashiv Amrapurkar, the most relevant villain after Gabbar Singh is gone... Reminds me yet again that life is too short. Love hard. Love more," she said.
