Chennai, Nov 14 : The title of director Mano Karthikeyan's upcoming film 'Jango' which the filmmakers claim is India's first time loop-based science fiction film, actually comes from the Turkish language. Talking to IANS, director Mano said, "The word 'Jango' in Turkish means to 'awaken'. My film has a connection with both the word Jango and the act of waking up." Ask the director what the concept of time loop is and he explains, "When a period of time -- it could be an hour, a day, a week or a month -- keeps repeating itself, then you call it a time loop. For instance, in my film, a doctor wakes up one Monday and gets caught in a time loop. How he comes out is what the film is all about." The film, which is even difficult to conceptualise, was a challenge to shoot, says the director, who says that writing this script was very different and more challenging than writing other scripts. "When you deal with a time loop film, the same situation will appear again and again and yet, you have to showcase them in a different and interesting manner each time so that the audience understands that this is a loop," says Mano. Produced by C.V. Kumar, the film, which features actors Sathish and Mrinalini Ravi in the lead, has music by Ghibran and cinematography by Karthik K. Thillai. /IANS
