It was the first Hindi film to gross over INR 1 billion.

Aamir Khan was originally given the role of Prem, but he refused to act in the movie, because he didn't find the script appealing. Salman Khan who was going through a bad career phase was then signed. The movies massive success, revived Salman Khan's career, which was originally doomed with successive flops.

HAHK was a trend setter for non-violent and NRI based films.

Filmmaker Karan Johar named it as the one film that changed his life. He said, "After seeing Hum Aapke Hain Koun..! I realized Indian cinema is about values, tradition, subtlety, romance. There is so much soul in it."

Lata Mangeshkar, who sang more than 10 songs in the movie, had long retired from accepting awards, but the public demand for the song "Didi Tera Devar Deewana" was such that she received the Filmfare Special Award that year.

Painter (Late) M. F. Husain was reported to have seen the film 85 times.

The film also won the National Film Award for Best Popular Film Providing Wholesome Entertainment.

The film was originally released in only a small number of theaters that agreed to upgrade their facilities. Due to widespread demand for the film after release, many other theaters upgraded in order to get the film. As a result ticket prices were raised, and more people came back to theaters who had been lost to television.

The music parts during the song "Joote Do Paise Lo", are the instrumentals of the songs, "Kabootar Ja Ja" and "Aja Sham Hone Ayi".

Both these songs are from Sooraj Barjatiya's previous film "Maine Pyar Kiya".

It was a remake of Rajshri's 1982 film 'Nadiya Ke Paar'.

The film was dubbed into Telugu as Premalayam.

The track "Didi Tera Devar Deewana" is said to be inspired by Ustad Nusrat Fateh Ali Khan's song "Saare Nabian".

Ugress song "Manhattan Sapphire" sampled the song "Joote Dedo, Paise Lelo".

The song "Dhiktana (Part 1}" was sampled in the song "We Got More" by Luniz feat. Shock G. The flute part. The song was featured in the Hollywood movie Don't Be A Menace in South Central While Drinking Your Orange Juice.

The film recorded highest number of footfalls by any bollywood films.

Before Madhuri, Sooraj Bartajya was about to sign Nikki Aneja.

Adjusted for inflation, this is one of the highest grossing Bollywood movie of all time, with collections upto 134 cr, which today would equal to approximately 700 crore.

"Jute Lo Paise Do" song set the trend of hiding bridegroom's shoes in wedding in Nepal . There were no such tradition before that.

Dee Dee Tera Devar was remixed as Ladies in a Frenzy Fridge in the album Streets of Bollywood by (Metz & Trix).

Beat Gates song "Tribal Drums" sampled the song " Maye Ni Maye" . This was released in the International album "Bangalang".

KenRock song "Big Drinkah" is a cover version of "Didi Tera Devar Deewana".

Rajesh Khanna was offered Alok Nath's role but declined it as he did not want to act.

Salman Khan is shown to be loading a 35mm film into a Camera, so that he can take pictures of Madhuri Dixit with the rest of the Family. This was the current technology for taking pictures during the 1990's, where the film roll would need sending to a development lab to print.

Anupam Kher was suffering from facial paralysis at that time and shot the drunken act of Sholay to cover up for his sickness.

The 14-song soundtrack, an unusually large number, is also one of the most popular in Bollywood history, with popular singer Lata Mangeshkar lending her voice for 11 of the 14 songs in the film.

It made a lasting impact on wedding celebrations in India, which often include songs and games from the film.

Director/writer Sooraj Barjatya devoted one year and nine months to write the screenplay of the film.

Barjatya spent the first five months trying to write another Maine Pyar Kiya, but then started over after his father Rajkumar Barjatya suggested that he rework one of the family company Rajshri Productions earlier offerings.

Barjatya used musical numbers to avoid treating some situations in a cliché manner, which resulted in so many songs that there were complaints during initial screenings of the film concerning its length and number of songs.

Barjayta's grandfather and the company founder Tarachand Barjatya, loved the song "Dhiktana" so much that the film was nearly given that title.

From conception to finished product, the film took four years.

Madhuri Dixit was paid a salary of Rs. 27,540,000 for playing the role of Nisha.

The finished soundtrack included an unusually large number of songs at 14 (15 if we count the sad version of the song Mujhse Juda Hokar which appears in the movie but not on the Music Album), and the song "Hasta Hua Noorani Chehra" (from the film Parasmani), that was used when the characters play a game.

The bright purple jaded satin saree with a backless khidki-blouse that Madhuri Dixit draped in "Didi Tera Dewar Deewana" was reported to have cost Rs. 1.5 million (US$23,000).

Designed by Anna Singh, the saree that Dixit wore in "Didi Tera Dewar Deewana" was described as one of the "most talked about sarees" by both The Tribune and The Times of India.[18][19] It became popular and was made available for purchase in various shops around the world, with it selling in large numbers.

With increasing appeal, the subsequent film's poster showed only Dixit in the purple saree whereas initially she was placed besides Khan.

The 2012 romantic comedy film "Shirin Farhad Ki Toh Nikal Padi" also used the same purple saree in their film's poster as was worn by Dixit.

This film, in addition to the following year's Dilwale Dulhania Le Jayenge, contributed to an increase in Indian cinema attendance of 40% in just two years.

It started Bollywood's "big-fat-wedding-film" trend.

In 1998 a theatre company in London, where the film had played for a year, staged a production based on the film titled Fourteen Songs, Two Weddings and a Funeral.

Redo, an Indian Spitz who played Tuffey, received favourable recognition. He was included in the "Best pets in Hindi films" list compiled by Daily News and Analysis.

After the film, Redo (Indian Spitz dog who played 'Tuffy') was reportedly adopted by actress Madhuri Dixit.

Early reviewers of "Hum Aapke Hain Koun..!" predicted that it would be a huge flop; hence the industry was stunned when it went on to become the most successful film of all time up to that point.

Actress Madhuri Dixit charged a higher fee than Salman Khan for this movie.

Movie is shot at Tamil Nadu's Nilgiri Hills, Ooty.

During the scripting of the film, Juhi Chawla asked Sooraj Barjatya if she could do the film. Sooraj replied that the casting was done and Madhuri was signed.

The antra of Ram Laxman's song from film TARANA (1949) "Gunchey Lagey Hain Kehne" gets recycled in a very intelligent manner by him only for the mukhda of "Maye Ni Maye" in HUM AAPKE HAIN KAUN (1994).

The song "Yeh ladka haaye allah, kaisa hai deewana" from Hum Kisi Se Kum Nahin has a tune when a marriage procession comes on the screen. Now listen "Yeh mausam ka jaadu hai mitwa" a song from the film "Hum aap ke hai kaun". The same tune has been used in whole song. A few tunes from the movie "Maine pyar kiya", is also used in "Hum aap ke hai kaun" at different places.

The scene which portrays Dixit walking down the stairs with Khan remaining stunned gapping at her was pointed out as an "iconic scene".
