Development Priyadarshan had earlier worked as a second-unit director, along with
Siddique,
Lal, and
Sibi Malayil, on
Manichitrathazhu (1993), which was directed by his friend
Fazil. Priyadarsan said
Mohanlal wanted to revive Sunny and was looking for a suitable subject and storyline. He said, "I had been telling [Priyadarshan] that he should revive Sunny as I felt that he was a character with immense potential for a new film; someone who can fit into any background or period. In this movie, Sunny reappears, a little older, but no less wacky than in his previous outing." The film is not an official sequel to
Manichitrathazhu, but Mohanlal portrays the psychiatrist Dr. Sunny Joseph, the character he acted in
Manichitrathazhu. About the genre, Priyadarshan described: "It is more of a
thriller and a
whodunit. To maintain the feel of the theme, there is no
slapstick comedy or forced attempts at humor. At the same time, I have infused humour into some of the scenes to ease the tension". According to the director,
Geethanjali is a psychological thriller set in a supposedly-haunted bungalow. Since the story has a Christian backdrop, he engaged screenwriter
Dennis Joseph to help with the dialogue.
Shobana, who played Ganga in
Manichitrathazhu was to make a guest appearance to introduce Dr. Sunny as the psychiatrist who cured her. However, that plan did not work out.
Geethaanjali was an official remake of the 2007
Thai film
Alone.
Casting Mohanlal reprised the role of Dr. Sunny Joseph, the protagonist in
Manichithrathazhu. The production team were looking for a heroine; they shortlisted a few people from the
Tamil,
Telugu, Malayalam, and
Hindi film industries during pre-production in June 2012.
Keerthy Suresh, daughter of veteran actress
Menaka and producer Suresh Kumar was selected for her debut lead role; she has earlier appeared as a child artiste in films
Pilots (2000),
Achaneyanenikkishtam (2001), and
Kuberan (2002), and in a tele-film by Suresh Krishna. Her father Kumar is a family friend of Mohanlal and Priyadarshan.
Nishan K. P. Nanaiah was cast as Anoop, the fiancée of the character acted by Keerthy Suresh. Actor
Innocent made a comeback to films with
Geethanjali after his cancer treatment, he agreed to act on the insistence of Priyadarshan and Mohanlal and allotted ten days for the shoot.
K. B. Ganesh Kumar was also signed in a role. Although Innocent and Ganesh appeared in Manichitrathazhu, they portrayed two new characters in
Geethaanjali. Late actor-director
Cochin Haneefa's twin daughters Safa and Marwa played the childhood of Geetha and Anjali. They have no dialogue and are only seen in a song sequence.
Suresh Gopi reprised his role as Nakulan in a cameo appearance. It was the first time Priyadarshan worked with veteran actors
Madhu,
Siddique, and
Harisree Ashokan. Priyadarshan began initial filming with two units—one at
Kovalam and another on a set at the
Pothencode palace. He tried to finish the shoot by 20 August, which left three weeks to complete
post-production. The film was shot on locations in and around Thiruvananthapuram and
Chitranjali Studio. The film's makers had initially planned to make the film in
3D format, but this was abandoned because of the cost of production and the technology was time-consuming and filming would take much longer than planned.
Tirru was the
director of photography. The music for the film was provided by
Vidyasagar and the film was edited by
T. S. Suresh. Lalgudi N. Ilaiyaraja was in charge of the art department. ==Release==
