The Director, Hrishikesh Mukherjee, filmed almost the entire film around his own bungalow at Bandra, in Mumbai in 40 days.
The song "Sab Golmaal Hain" was used in the film Hera Pheri.
Hrishikesh Mukherjee was inspired by a Bengali film, Kancha Meetha, whose hero similarly fabricates one lie after another.
Amitabh Bachchan had a cameo in this movie. He was also seen in the 2012 remake of this movie (Bol Bachchan) making his cameo in the promotional music video.
This movie, once being remade into Bol Bachchan, it was again remade into a Telugu film, Masala.
