The Rajpurohit warns everyone not to go near Manjulika's room, advising that it should only be opened on Durgashtami by a royal family member reborn to rid them of the ghost.

The Rajpurohit returns with sacred oil to destroy Manjulika's spirit, and the night before Durgashtami, they gather at the site where her body was burned 200 years ago.

Ruhaan cleverly manages to exorcise the spirit that had possessed both Mallika and Mandira, finally learning that it was the ghost of Prince Debendranath himself, who had been killed by execution which was ordered by his father on account of his feminine hobbies and transgender identity.

Following this, the king, knowing daughters did it to steal the throne, exiled them both from the kingdom and announced that Manjulika will be known for killing her brother brutally to the public, and Anjulika's existence in history will be erased.

It was finally revealed that it was Debendranath's spirit that was causing all the disturbances by possessing his sisters' reincarnations, Mallika and Mandira, to trick everyone into killing them.

The cast also features Vijay Raaz, Rajesh Sharma, Manish Wadhwa, Sanjay Mishra, and Ashwini Kalsekar.

[11][12] On 9 March 2024, in Mumbai, the cast and crew of Bhool Bhulaiyaa 3 gathered for an inaugural muhurat puja ceremony to mark the beginning of principal photography.

Against doctor's suggestions to get a steel plate and rest for 3 months, he opted for minor surgery that allowed him to honor his commitment to the film.

[16][17] The film's production involved extensive planning and coordination, with key members Bhushan Kumar, Bazmee, and Aaryan actively engaged in discussions and preparations.

A massive set was erected in Film City, Mumbai, specifically for the song, which involved over a thousand background dancers with choreography done by Ganesh Acharya.

[23] In this schedule, Aaryan rode a bullet on Howrah Bridge,[24] with Prantika Das and with Arun Kushwah at Victoria Memorial.

[27] Following this, Bazmee filmed scenes at the Park Street Graveyard and Nonapukur Tram Depot, and finally concluded the shoot at Laha Bari in Central Kolkata.

The next schedule was kicked off on 1 July 2024, in Orchha, Madhya Pradesh[34][35] with Kartik Aaryan, Vidya Balan, Madhuri Dixit, Triptii Dimri, Rajpal Yadav, and others.

The "Title Track" and "Ami Je Tomar" song originally composed by Pritam were recreated once again after Bhool Bhulaiyaa 2.

[57] Bollywood Hungama rated the film 4.5 stars out of 5 and wrote, "Bhool Bhulaiyaa 3 is a well-made horror comedy which works due to its performances, taut script, creative execution and above all, an unpredictable climax.

"[58] Sukanya Verma of Rediff.com rated the film 3/5 stars and opined "A gleefully hammy Madhuri and Vidya's volley of death stares and evil laughs engage in a ruthless glamorous tug of war in Bhool Bhulaiyaa 3".

[59] Renuka Vyavahare of The Times of India rated 3.5/5 stars and wrote "The movie is unabashedly entertaining, cheesy, and wild, with moments that will have you laughing out loud.

"[60] Vinamra Mathur of Firstpost rated the film 3/5 stars and wrote "Bhool Bhulaiyaa 3 could be savored taste; for those wanting to see romance have Aaryan and Dimri, for those waiting to see the OG Manjulika have Balan at their service, for anyone enamored by Dixit, she brings back the memories of Devdas with her thunderous aura and nimble moves.

[61] Anuj Kumar of The Hindu says Bhool Bhulaiyaa 3 is a drab horror comedy where talented actors like Madhuri Dixit and Vidya Balan have been underutilized.

He further says "Kartik Aaryan is the lifeline who keeps the film alive with his situational humour but director Anees Bazmee has faltered between sticking to stereotypes and taking a progressive step."

"[64] Udita Jhunjhunwala of Mint opined "The dynamic between Madhuri Dixit and Vidya Balan is an opportunity wasted in the long film, which is high on concept but low on mood".

[65] Abhimanyu Mathur of Hindustan Times writes "A brave climax attempts to elevate this otherwise middling horror comedy.

The film simply tries to sell a brand through nostalgia, using a new(er) rendition of Ami Je Tomar and Vidya Balan.

"[67] Nishad Thaivalappil of News18 rated 2/5 stars and opined "The film features unexplained flashbacks and the mediocre jokes and predictable jump scares make it a rather dull watch.

"[69] Ritika Handoo of Zee News rated the film 3 out of 5 stars and highlighted "What deserves a special mention here is the twist-filled climax.

"[71] Amit Bhatia of ABP Live rated the film 3/5 stars and said "Vidya Balan and Madhuri Dixit breathe energy into the narrative, and while the comedy isn't as punchy as hoped, the story's twists and moral message manage to engage.

Dominated by dull comic punches and references, unnecessary and forced song sequences, and complete mutilation of the Bengali language and dialect, the film fails to keep the audiences at the edge of their seats.
