The film stars Vijay Sethupathi and Remya Nambeesan, with Aadukalam Naren, Karunakaran, Jayakumar, Pooja Ramachandran, and Bobby Simha in supporting roles.
At first, Michael is confused and scared, and his fears are confirmed when he discovers that a spirit has possessed his boss Shanmugam's daughter.
When his boss questions him, Michael explains that he had been to deliver a pizza to a customer named Smitha in a bungalow and recounts the events he encountered there.
Bobby suddenly disappears from the front entrance and is found inside the house, murdered in the same room as his wife, with two slices of pizza now missing.
Michael encounters the couple's child, "Nithya," identical to the spirit's name, allegedly possessing the boss's daughter.
When a couple of officers arrive at the bungalow, they reveal that four people died in that house: Smitha, Bobby, their young daughter, and a girl named Anu.
Shanmugam, who has diamonds worth around 20 million hidden in his restaurant, hides them in a candy box and asks Michael to deliver them to his house.
After the phone call, Michael goes to deliver a pizza to a house and encounters a series of events similar to the story he had narrated.
[5] Vijay Sethupathi, when asked how he was cast in the lead role, replied, "I used to regularly leave my photographs in the film institute.
[10] Karthik Srinivasan of Milliblog wrote, "Santhosh Narayanan delivers on the promise he showed in Atta Kathi".
[1] N. Venkateswaran from The Times of India gave 4 out of 5 stars and wrote that director Karthik Subburaj displayed a "strong control of the medium and gives abundant display of his narrative skills", going to add: "If he maintains the quality of his menu and future offerings, Karthik [...] is sure to become one of Kollywood's top directors".
The former claimed that the second half of Pizza has a "reasonably enjoyable tanginess, but to get to that you have to sit through the protraction of the first" and that "the screenplay [...] doesn't render much help",[18] while the latter concluded that the film displayed "signs of a craftily executed thriller, but falls short of satisfaction due to erratic narration", giving it 2.5 out of 5 stars.
Along with Pizza, he scored back-to-back successes with Sundarapandian (which featured him in a negative role) and Naduvula Konjam Pakkatha Kaanom in the same year resulting in a rise in his popularity.
[24][25] Film critic Baradwaj Rangan stated that Sethupathi had become "[...] sort of [an] indie-film star, the first ever in Tamil cinema".
[27] Pizza and Kadhalil Sodhappuvadhu Yeppadi became trendsetters and sparked a short-lived boom of short filmmakers making their feature debut in Tamil cinema.
[30] The original film was dubbed in Telugu,[31] remade in Kannada as Whistle (2013),[32] in Hindi under the same title in 2014,[33] and in Bengali as Golpo Holeo Shotti (2014).
