Geethaanjali
Geethaanjali is a 2013 Indian Malayalam-language horror film directed by Priyadarshan and written by Abhilash Nair, with dialogue by Dennis Joseph. Though promoted as spin-off of the 1993 film Manichitrathazhu, it was an adaptation of the 2007 Thai film Alone which was loosely based on the novel Elephants Can Remember. Mohanlal reprises his role from Manichitrathazhu and Suresh Gopi appears in a cameo role. It also features Keerthy Suresh, Nishan, Siddique, Madhu, Swapna Menon, Innocent, and K. B. Ganesh Kumar. In the film, psychologist Dr. Sunny Joseph arrives at a mansion to treat Anjali, who is haunted by her deceased twin sister Geetha, and investigates the paranormal activities. It marked the Malayalam and film debut of Keerthy Suresh. The film was originally planned to be shot in 3D and Auro-3D formats but this was abandoned because the technology was time-consuming and only a few theatres in Kerala were equipped with Auro sound equipment at that time. Principal photography commenced on 6 July 2013 at Thiruvananthapuram and was completed in September. Most of the filming took place at the Chitranjali Studio and in and around Thiruvananthapuram. The cinematographer was Tirru and editing was done by T. S. Suresh. Geethaanjali was released worldwide on 14 November 2013. The film being an official remake of Alone was undisclosed before release, as a result, it was criticised as an imitation of Alone and its source material, the novel Elephants Can Remember and other Indian films adapted from the film or novel. Mohanlal's performance, the cinematography and the graphics received praise. Plot

It is believed that Anjali's twin sister Geetha has committed suicide. Anjali is betrothed to Anoop, a member of a prominent family who works in Mumbai. When her mother falls from a terrace and is bedridden paralysed, Anjali and Anoop go to her house in Arackal, Kerala. Once there, Geetha's spirit begins to haunt Anjali, which disturbs her a lot. Within days, a series of horrifying incidents occur. Anoop contacts Nakulan; in order to reach Dr. Sunny Joseph. Sunny eventually arrives from Machu Picchu to treat Anjali and to help her out of her crisis. Since everyone believes the house to be haunted, the family buys a new house. The future owner of the house Vasu claims that he had seen Geetha in a car and wrote down the number on a file. He says that he could give it to them the next day, but he gets a phone call from Geetha's spirit asking him to meet her in the church next morning. He goes there and calls Sunny for help, but gets killed before Sunny could help him. Sunny then spots a car driving out of the church and follows it, but the killer already got out of the car before Sunny could spot him. Anjali tells Sunny that Geetha had committed suicide after she learned that Anjali and Anoop loved each other. Sunny then seeks help from Kadalikkattu Thirumeni who too discovered that Anjali was possessed by Geetha's ghost. Gruesome events follow, including the death of Thambichayan, a caretaker at Arakal. Sunny tells everyone that the ghost haunting Anjali is just a psychological effect and not real. For some reason, he tries to postpone the marriage, but in vain. Anoop assumes that Sunny is trying to separate Anjali from him, and thus Anoop drives Sunny out of the house. It is then that he sees the death of Thambichayan who was caught in a fire from a cottage. On their engagement day, Sunny grabs Anoop and shoves him into his car. He drives to a small graveyard and tells Anoop that the so-called Anjali is actually Geetha, who has criminal intentions. In a flashback, it is revealed that Anjali and Anoop fall in love with each other, but Geetha misunderstands that Anoop loved her and she loves him back. Geetha became angry that Anoop is going to marry Anjali and not her, and decided to take revenge on Anjali. Sunny then shows Anjali's grave to Anoop and tells him the whole truth about her. The feeling of guilt in her mind led her to see Anjali wherever she goes, and all the horrible incidents that happened were just illusions seen by Geetha. Vasu was actually killed by Thambi, the only person who knew the truth, apart from Geetha and her mother. It is also shown that it was Geetha who accidentally shoved her mother off the terrace, when she was told that Anjali's spirit was in the house. Thambi is later killed by Geetha so that there is no way anyone could unravel the truth. Sunny, still unsure, tried to postpone their marriage until he had collected enough evidence to reveal the truth. Hearing this, Anoop storms into the house and accused Geetha of taking Anjali's name. Geetha tries to kill Anoop when he says that he does not want her anymore. She finally revealed that it was she who killed Anjali during the argument in the beach (while she conveniently concocted a different version when Sunny had earlier asked about the beach incident). Anoop almost gets paralyzed by Geetha and is about to be killed. Sunny breaks into the house and rescues Anoop, but she takes a gun and tries to aim at them but as the gun was not loaded, it didn't fire. An image of Anjali's spirit appears in Geetha's mind (on a mirror) and prevents her from shooting Anoop. Geetha is killed by a fire in the house, and Anjali's "spirit" watches over Geetha while she is dying. Later, Geetha's grave is built alongside Anjali's, and Anoop, his family, and Thankappan thank Sunny for helping them.
