A remake of the 2011 Marathi film Mala Aai Vhhaychy!, it stars Kriti Sanon in the eponymous lead who opts to be a surrogate mother for a foreign couple.

Pankaj Tripathi, Sai Tamhankar, Manoj Pahwa, Supriya Pathak, Evelyn Edwards, and Aidan Whytock appear in supporting roles.

Pretending to leave for an outdoor film shoot lasting nine months, Mimi goes into hiding at her friend Shama's place.

John and Summer threaten Mimi with legal action, and she relents for Raj's sake so that he wouldn't have to be dragged to court.

They decided to adopt her, explaining to Mimi that her affection for Raj made them realize that motherhood extended beyond genetic ties.

The film was officially announced in August 2019 followed by a poster release and Sanon and Pankaj Tripathi were reported to feature in lead roles.

[6] In an interview with India Today, Dinesh Vijan stated that Mimi was a tale based on true events unlike poignant stories.

[6] Actress Sai Tamhankar was roped into playing a pivotal character in the film, sharing screen with Tripathi.

In June 2020, Utekar confirmed that five days shoot was pending which included an introductory song featuring artists from United Kingdom.

[citation needed] The original score and soundtrack were composed by A. R. Rahman and featured lyrics written by Amitabh Bhattacharya.

[20] The soundtrack was released by Sony Music India on 16 July 2021, along with the song "Param Sundari" as the lead single.

[29] Renuka Vyahare of The Times of India gave 4 (out of 5) stars and said "Mimi picks a relevant topic and turns it into an engaging, empowering and compassionate tale on humanity and motherhood".

[30] Taran Adarsh, in his review for Bollywood Hungama, wrote "Mimi is a heartwarming saga, aimed at families and it will keep the audience thoroughly entertained.

In fact, as you see her shoulder the film with her craft, you will also see her deliver her career-best performance; Mimi is Sanon's labour of love all the way".

In the climax, she is able to summon a wellspring of emotion but largely, her efforts are undermined by the script and her own inability to let go of synthetic Bollywood glamour.

"[33] Jyoti Kanyal of India Today gave 2.5 (out of 5) and said "Mimi is a great attempt at bringing a social taboo like surrogacy to the center stage.

[34] Anna M. M. Vetticad of Firstpost gave 1.5 (out of 5) saying "Writer-director Laxman Utekar's new Hindi film is a muddled take on motherhood with clarity only on its conservative mission to condemn abortion.
