The blockbuster song Jhooma Chumma was originally recorded for the Ramesh Sippy shelved film Ram Ki Sita Shyam Ki Gita. It was to star Amitabh Bachchan and Sri Devi in double roles. When the film stopped Mukul Anand made a personal request to use the song in his film Agneepath. The song was going to be filmed on Amitabh and Archana Puran Singh. But Mukul felt Amitabh's character should not sing and dance in the film. That is when the song was shifted to Hum.
There was a controversy regarding the song 'Jhumma Chumma De De', as in the film Thanedaar which released a year before, there was a song 'Tamma Tamma Loge', which had a similar tune, both songs were actually a remake of " Tama" by Mory Kante.
The most successful film amongst the Mukul Anand trilogy with Bachchan which includes Agneepath and Khuda Gawah.
This film was later modified and made in tamil titled Baasha starring rajnikant. Danny's character in tamil film is similar to hindi (including the get up) and was played by raghuvaran.The film was a massive hit in tamil.
Gulshan Grover was signed for the film and was extremely happy as it would be the first time he worked with Amitabh Bachchan. But Gulshan was asked to give bulk dates and he could not. He was about to leave for South Africa for Shikaari. He could not back out of that film. He ended up losing the role to either Shiva or Annu Kapoor. When the film was launched all the character actors had different looks. Anupam was in a police uniform, Danny was dressed as dock worker in black clothes, Kader Khan dressed as a pathan. The photo's may have been for the film's publicity.
