Harikrishnans is a 1998 Indian Malayalam-language mystery buddy comedy film written and directed by Fazil. The film was produced and distributed by Suchitra Mohanlal under the production company Pranavam Arts, starring Mammootty and Mohanlal in the title roles. Juhi Chawla, Innocent, Shamili, Nedumudi Venu, Cochin Haneefa, Jagadish, Maniyanpilla Raju and Kunchacko Boban play the supporting cast. The film received a great pre-release hype due to the combined screen presence of Mammootty and Mohanlal after 8 years. It was released theatrically on 4 September 1998, coinciding with Onam, to critical acclaim and emerged as a commercial success. It was the highest-grossing Malayalam film of the year. It was later dubbed into Tamil with the same name.

The film initially had two endings when released, where the heroine chose Mammootty in one version and Mohanlal in the other one. This was an attempt by the filmmakers to satisfy the fanbases of both Mammootty and Mohanlal, who were each popular in different regions of Kerala. However, only one version was submitted to the Central Board of Film Certification (CBFC) for censorship approval. The producers were embroiled in legal actions after that, but the gimmick helped the film to bring in millions of rupees. This was an upturn for the Malayalam film industry, which had been generating unsuccessful films for quite some time.

The Harikrishnans are one of the most famous lawyer duo in India. They head the organization called Harikrishnan Associates, which consists of around 300 lawyers. They get engaged in a murder case of Guptan, who was allegedly killed by a hearing and speech impaired woodcutter, Gabriel. Gabriel is a friend of Hari's sister and Harikrishnans become the defence lawyers upon her request.

The Harikrishnans begin an investigation and come across Meera, a friend of Guptan. Both of them fall in love with her. After some trouble over the matter, they rediscover their friendship and get involved in the case again. They discover that Guptan actually died due to poisoning by his relatives who were doctors who wanted to amass his wealth. The culprits are captured and Guptan's elderly father accepts Sudarshanan, a former student of Guptan, as his son and successor to the property.

In the end, Meera opts for a random method to choose her life partner, as she is equally fond of both Harikrishnans. She decides to toss a leaf, with the name it lands on being designated as her friend, who would then choose who should marry her. The leaf lands on Hari's name, and it is presumed that she makes him her friend. It is likely that Hari would suggest Krishnan as the one to marry her.

In the uncensored cut of the film, the leaf lands on Krishnan's name, and it is presumed that she makes him her friend. It is likely that Krishnan would suggest Hari as the one to marry her.

There was another ending planned with Shah Rukh Khan. He was proposed to do the role of the lover of Meera. But due to some technical problems it was cancelled.
