Disco 84 was sampled in the song Tiger Bomb Express by Romanowski, from the album Tiger Bomb Express.
Panic struck on November 11 1983 when Aaj Kaa MLA Ram Avtar was launched with a 10 day shooting spell. The director Dasari Narayana Rao had approached Dilip Kumar for the film but he declined. He also approached Amitabh for a another film, but he also declined. At a party at Srinagar, before a crowd of 100 people, Dasari Narayana Rao proclaimed he would make a bigger hit than Avtaar with Rajesh Khanna. The film was a remake of Eedukonadalu . It dealt with a chief minister and the Congress government had tried to ban it before the elections that brought NTR into power. But not many knew about Aaj Kaa MLA Ram Avtar before hand. The launch and mahurat of the film came as a shock, specifically to T. Rama Rao who was a rival of director Dasari Narayana Rao. On the same day the producer of Inquilaab A. Veeraswamy made a frantic phone call to Amitabh. He was angry and yelling, stammering over his words. Amitabh asked him to calm down and come down to Delhi to meet him and speak about the matter. A.Veeraswamy, T. Rama Rao, S.Ramanathan, A. Poornachandra Rao all boarded a emergency flight to meet Amitabh in Delhi. Upon landing, A.Veeraswamy told Amitabh that Dasari Narayana Rao launched Aaj Kaa MLA Ram Avtar, which was a remake of Telugu hit MLA Eedukonadalu. It was a plan to sabotage Inquilaab. Amitabh was said to have laughed it off not taking it seriously. When A. Poornachandra Rao explained further how bad the situation was, Amitabh was shaken. Aaj Kaa MLA Ram Avtar was actually planned to be launched in January 1984. When there was a slight delay in Inquilaab due to Amitabh severely injuring his left hand during Diwali celebrations, Rajesh Khanna contacted Dasari Narayana Rao. He wanted to life the entire second half of Inquilaab and add with to to Aaj Kaa MLA Ram Avtar. The producer T. Kranthi, Dasari Narayana Rao and Rajesh Khanna had plans to shoot and complete the film before Inquilaab could release. They were all aware Inquilaab would take another 8 months due to Amitabh canceling Tinu Anand and Prakash Mehra's films in November, December, January. Amitabh was taken back by the situation, but a doubt lingered in his mind. He questioned the credibility of the situation. T. Rama Rao made a phone call to writer Dr. Rahi Masoom Raza. He was the dialogue writer for Inquilaab and Aaj Kaa MLA Ram Avtar. Dr. Rahi Masoom Raza spoke to Amitabh and confirmed the entire story. Amitabh was shaken but could understand why Dasari Narayana Rao would join hands with Rajesh Khanna. Dasari Narayana Rao had approached Amitabh for another film which Amitabh declined. He then approached Amitabh again for Aaj Kaa MLA. Amitabh declined the offer in favor for A.Veeraswamy's Inquilaab. Amitabh realized how serious the situation was and decided to immediately shoot Inquilaab against doctors orders. Amitabh would need constant medical attention on the sets and the bandages could not be removed no matter what. So, T. Rama Rao decided Amitabh's character would constantly have one hand in his pocket at all times. Amitabh called Prakash Mehra and explained the situation to him. Prakash Mehra gave Amitabh the go ahead to shoot Inquilaab before Sharaabi. He would not be angry about this. So just 10 days after Aaj Kaa MLA Ram Avtar was launched on November 21, Amitabh flew to Madras and shot for the film inquilaab nonstop. The situation was such that the Mumbai actors were offered 3 times more money in cash if they could give immediate shooting dates and complete their scenes fast. Prakash Mehra blasted Rajesh Khanna in the print. Mehra called Khanna petty for playing this dirty game with Amitabh. Amitabh hand was all black from being burnt. He needed to go to USA for skin grafting. Now he could not do that immediately due to Rajesh Khanna trying to sabotage Inquilaab. Rajesh Khanna got word about Inquilaab's new progress and promised immediate dates for the film. But for unknown reasons Aaj Kaa MLA Ram Avtar got postponed slightly making it release after Inquilaab.
Nirupa Roy's picture was used in the film as Amitabh Bachchan's deceased mother. She was seen in one scene as flashback.
While the movie was being filmed, in an unrelated accident, Amitabh Bachchan had a firecracker go off in his hand. Surgical correction was incomplete during the rest of the filming, so he wears a handkerchief or hides his hand in many scenes.
The film released in 1984 when Amitabh had in real life too joined politics like in this film.
