Raakhee Gulzar had been offered the role opposite the senior Bachchan role. When she found out that Hema and Zeenat, both her contemporaries, were acting opposite the two junior Bachchan roles, she backed out and another Amitabh favorite - Waheeda accepted the role. Hema then opted out due to her pregnancy and Parveen replaced her.
Amitabh shot for Mahaan in Nepal. This is what he stated "I visited Nepal in 1954. We were still living in Allahabad, and had taken a trip with the family to Patna and across the river in a steamer to Muzaffarpur. Babuji had desired a meeting with some of his very close literary contemporaries. Having done that we flew from Patna airport to Kathmandu, the Capital of Nepal, in a twin engined propellor Dakota aircraft, that warhorse of the WW 2 era, and perhaps those that have interest in aeronautics, the most sturdy and long lasting aircraft to date .It was my very first experience on a plane, and of course my very first visit to a foreign country. The excitement generated was beyond compare. I was in some very superior space during those times, my worth and value among my friends reaching its peak.Kathmandu, in 1954 was in the process of development. It was bare and scarce and basic. Babuji's dear friend Maharaj Kishen Rasgotra, of the Indian Foreign Service, was posted there as 1stsecretary in the Indian Embassy. The Ambassador then was Shri Bhagwan Sahay, a most senior old time ICS, Indian Civil Service, as it was called during the time of the British Raj, and also a great admirer and friend of Babuji.The landing strip at the airport was still a mud and earth track. And I still remember being told that the only metalled road in Kathmandu then, was the road from the Indian Embassy to the Royal Palace, then of King Tribhuvan, subsequently then of King Mahendra his heir, and after, to that tragic incident in the Palace when the heir to King Mahendra,who was the ruler, and his entire family being shot and killed by his own son.The Royal family had been admirers of Babuji's poetry, and later during my more recent trips to the land, always gave us audience.Two aspects of that Nepal visit remain still in memory - ping pong balls from China, that were available there ; an imported delicacy, so vital for us to talk about - the possession of imported goods having stature and value in social conversation, and the bandgala Jodhpuri jackets, the formal attire of India, which my Mother had made for us, my brother and me, prior to the visit, because we were told that would be occasion to wear it at one of the formal ceremonies. The ceremony was the Investiture Ceremony of the Ambassador of India to the King of Nepal, where Diplomatic credentials were presented to the host nation by the diplomatic mission of another. We had the great honour to be a part of the audience at that prestigious moment !!The jacket top was a greyish bluish spotted material and colour, the trousers were black. It was our most prized possession ! For someone that possessed no formal attire, or to be more precise, barely a pair of trousers and shirt in my clothings, this acquisition was supreme !! IIn Nepal the other memory was of poetry symposiums at various homes of dignitaries, politicians and people of eminence. Some who had spent time during revolts in prison, often talked of how my Father's works inspired them during their time in jail, and kept company with them. I remember that great big open space, a large maidan in the centre of the city, Tundi Khel. And the only Nepalese that I learnt then which has remained with me since :Kankdo kayo ! Kausto lago ? Ramro lago ramro lago !!( Did you eat the cucumber ! how was it ? it was good, it was good )And .. in a scene in my film 'Mahaan', where I play 3 characters, I used these words in the character that has Zeenat Aman opposite ... the scene in a white suit and red sunglasses, and the legendary Ashok Kumar with us, where he has gathered some prospective suitors for his daughter .It is quite remarkable that what was stored in the computer memory of the brain in 1954, was given presence in 1981 (?) or about !! Apparently, during my recent meetings with the medical profession in connection with a campaign that I am aiming to associate myself with, I gained the knowledge that, old time memories remain fresher as we age, than what transpired a day ago !!Coincidentally and
The films story line of a man on a run after being charged for murder and living in different name was similar to earlier films like Tumsa Nahi Dekha 1957,Sanam Teri Kasam 1982 and later on Zamane Se Kya Darna 1994.
The acting style (dialog delivery, voice, expressions)of Amitabh Bachchan when he see a cobra near the end of the film, were repeated once again. In Toofan, Amitabh also encounter a cobra, he delivers the scene in the same exact way as he did in Mahaan.
The makers of this film first had approached Jeetendra to play the triple role in this film, as Jeetendra was acting in many South films at that time, but he was very busy with other South films he told the makers to take Amitabh Bachchan for this film and Jeetendra called Amitabh Bachchan to request him to do Mahaan.
RD Burman used the antara of the song "Yeh Din Toh Aata Hain" for his international album Pantera. For his international album , he had a song called "Carnaval". He used the antara of the song "Yeh Din To Aata Hain" and gave it a Spanish feel.
Amitabh Bachchan the father in this film, in his own voice sings the song ' jidhaar dekhon teri tasveer, nazar aati hai ' to waheeda Rehman on the phone. This sequence was heavily critised and later that song was deleted from the film. It was in the VHS version released in 1983. It was also included in the Esquire released video "Yeh Hain Amitabh" . Later after 20 years, in Baghban there was a similar song sequence of Amitabh singing in his own voice on the phone to Hema Malini.
This was the final film released that featured both 阿米达普·巴强 and 阿姆贾德·汗. They would appear together for a scene in Ameer Aadmi Gharib Aadmi (1985) in which Bachchan plays himself, which was the last ever time that they appeared together.
The tune/rhythm of the background music in the scene where Amitabh is at the train station and running down the stairs with a glass of water, was recreated for Coolie. During the song "Accident Ho Gaya Rabba Rabba" in the part where Allah Rakha drops the garland in Amitabh's hands, has the same tune/ music as the above mentioned scene in Mahaan.
Hema Malini stated she wanted to start shooting for Mahaan , but the producers kept delaying the film with stupid excuses. They would say Amitabh hurt his leg, they did not have finance etc. This took a year away. Hema Malini wanted to have a child and opted out of the film. The film finally released when Esha Deol was 2 years old.
There is a song in this film Amitabh Bachchan sang in his own voice to Waheeda Rehman on the phone Jidhar Dekhun Teri Tasveer.....Many criticised about it. But after some 20 years in Baghbaan again Amitabh Bachchan is singing on the phone to Hema Malin. Main Yahaan Tum Ho Wahaan......
Amitabh suffered a injury while shooting the climax song Asli Kya Hain Naqli Kya Hain. He slid down the coir rope and the skin peeled off his palm. The shooting had to be postponed. Then while shooting in Delhi he had a severe asthma attack.
The song Har Chori Rani in the original VHS version had Amitabh Bachchan end the show staying who he is and then followed with a round of applauses from the audience with Mukhri shouting at him to get off the stage as he thought the play was disgusting and the scene ends with Mukhi saying to Amitabh in Hindi: "Just who do you think you are? Amitabh Bachchan?!" This scene was cut in the DVD version
Amitabh Bachchan convinced RD Burman to sing the song Yeh Din To Aata Ek din Jawaani Mein In his original voice.RD Burman would manipulate with his voice while singing as he felt his voice wasn't good as he has had tonsils operation when he was a kid.
The VHS version released in the international market in 1983 (which was pirated from a movie theatre) had extra footage for a few scenes. For example after the song "Har Chori Rani Yahan" Amitabh stand's on stage in front of audience and some from the audience says "Apne aap ko Amitabh Bachchan samajh tha hain kya". Many scenes were also missing in the international VHS version. The whole scene of Amitabh (Guru) meeting Ashok Kumar for the first time was edited out for unknown reasons. The scene prior to "Pyar Mein Dil Pe Maar De Goli" was edited to where Zeenat Aman says " chalega" in regards to accepting the comic Amitabh as her lover. She then declares her love for him and the song starts. The DVD version of Shemaroo had the proper scene prior to the song.
