Although it was a moderately successful film at the box office (it grossed $77,527,732.), it received "generally unfavorable reviews" according to Metacritic. In 2010 Gold Circle Films announced the production of two more entries in the franchise, The Haunting in Connecticut 2: Ghosts of Georgia (released 2013) and The Haunting on Long Island: The Amityville Murders. They noted, however, that neither film would be a direct sequel to The Haunting in Connecticut and would instead be self-contained films with unique characters.
In 1987, Sara Campbell (Virginia Madsen) is driving her son Matthew (Kyle Gallner) home from the hospital where he has been undergoing cancer treatments. Sara and her husband Peter (Martin Donovan), a recovering alcoholic, discuss finding a rental house closer to the hospital. On another hospital visit, Sara finds a man putting up a “For Rent” sign in front of a large house. The man is frustrated and offers her the first month free if she will rent it immediately.
The following day, Peter arrives with Matt's brother Billy (Ty Wood) and cousins Wendy (Amanda Crew) and Mary, and they choose rooms. Matt chooses the basement, where there is a mysterious door. After moving in, Matt suffers a series of visions involving an old, bearded man and corpses with symbols carved into their skin. The next day, Peter learns that the house was supposedly a funeral home; the room behind the mysterious door is a mortuary.
Matt tells another patient, Reverend Nicholas Popescu (Elias Koteas), about the visions. Nicholas advises him to find out what the spirit wants. Later, Matt finds a burned figure in his room who begins to move toward him. When the family comes home, they find a shirtless Matt with his fingers blood-covered from scratching at the wall.
The family begins to crack under the stress of Matt's illness and bizarre behavior. The children find a box of photographs, which show Jonah, a young man from Matt's visions, at a séance, emitting ectoplasm. Wendy and Matt find out that the funeral home was run by a man named Ramsey Aickman. Aickman also conducted psychic research and would host séances with Jonah as the medium. At one séance, all those attending, including Aickman, were found dead and Jonah disappeared.
Nicholas theorizes that Aickman was practicing necromancy in an attempt to control the dead and bind them to the house. That night, Nicholas finds human remains in the house and removes them. Matt awakens to find Aickman’s symbols carved into his flesh. He is taken to the hospital, where he encounters Jonah. Nicholas and Matt begin to have simultaneous visions. Everyone in the séance is burnt, after a flash of bright light. The barely alive Aickman told Jonah to get out of the house, concerned that the demonic presence will get him next. Jonah uses a dumbwaiter to escape, calling for help. Entering an unknown chamber, Jonah realizes that he has entered the crematory. The spirit traps Jonah in the crematory, and cremates him alive.
Peter and Sara learn that Matt's cancer treatments have had no effect. They then discover that Matt has escaped the hospital. Back at the house, Nicholas leaves a message telling the family to get out of the house immediately – Jonah's spirit was actually protecting them from the spirits. Matt breaks through the walls in the front room with an axe, revealing the dusty corpses Aickman hid in the walls. He forces Wendy and the children to get out, barricading himself inside and tearing down the other walls, as corpses begin to tumble into the room. The view switches from Matt to Jonah, who seems to be occupying Matt's body. Matt lights the bodies and the room on fire.
As the fire department arrives, Sara and Peter frantically try to get in to save Matt. The spirits, finally freed, disappear. Outside, everyone watches tearfully as the emergency crew attempts to resuscitate a dying Matt. As Matt slips away, he has a vision of himself standing in the graveyard where he sees Jonah, no longer appearing burnt. He seems about to follow Jonah when he hears his mother’s voice.
He returns to his body and Jonah's spirit leaves him. Matt's cancer disappears, and the house was rebuilt and resold with no further reported incidents of haunting.Virginia Madsen as Sara Campbell

Promotional material for the film claimed that it was "based on true events" experienced by the Snedeker family of Southington, Connecticut in 1986. Ed and Lorraine Warren claimed that the Snedeker house was a former funeral home where morticians committed necromancy and/or necrophilia with the corpses, and that there were "powerful" supernatural "forces at work" that were cured by an exorcism. Carmen Snedeker's claims of haunting by an "evil entity" and subsequent exorcism were dramatized in episodes of the television series A Haunting, Paranormal Witness and Mysteries at the Museum.
However, according to skeptical investigator Benjamin Radford, there is "little or no proof that anything supernatural occurred at the house". Radford wrote that author Ray Garton was employed by the Warrens to write the supposedly "true story" and was instructed by Ed Warren, "You've got some of the story — just use what works and make the rest up… Just make it up and make it scary."
Researcher Joe Nickell has dismissed the story as a hoax. Nickell noted that since Ed Warren died in 2006, some of his coauthors have admitted he "told them to make up incidents and details to create scary stories."
Filming began on September 10, 2007 in Teulon, and Winnipeg, Manitoba and it was released on March 27, 2009 in the UK, USA, and Canada. The film was later released over the course of nine months to other countries, and was shown at the Imagine: Amsterdam Fantastic Film Festival the April following domestic release.

The DVD material was produced and directed by Daniel Farrands, who also served as a producer on the film. The DVD release of The Haunting in Connecticut was the recipient of the Best Ghost Story award in Home Media Magazine's 2009 Reaper Awards ceremony held in Los Angeles in October 2009.
Review aggregator Rotten Tomatoes rated the film as "rotten", with a 17% approval rating based on 94 reviews and an average rating of 4.3/10. The site's consensus reads: "Though it features a few scares and some creepy atmosphere, The Haunting in Connecticut ultimately relies too much on familiar horror cliches to achieve its goals." Metacritic found the film had received "Generally unfavourable reviews", scoring 33 out of 100 based on 23 critic reviews. While the film was mainly criticized for its use of horror cliches and "jump" scare tactics, certain aspects of the film were praised by many critics. Particular credit went to the acting: primarily the performances of Gallner and Madsen. Film critic Roger Ebert said the film "is a technically proficient horror movie and well acted," though he gave the movie only two stars.
In North America, the film opened in second place (behind Monsters vs Aliens), averaging $8,420 at 2,732 theatres. Its final North American gross was $55,389,516, and it made a further $22,138,216 internationally for a worldwide total of $77,527,732.
