Casanova was launched on January 24, 2009 and its production is said to have been delayed due to the shooting of other movie of Mohanlal. The film has reportedly been shot in Kerala, Bangkok and Dubai. Currently, the film unit is shooting the climax of the film in Dubai. However, three musicians Gopi Sundar, Alphonse Joseph and Gauri are scoring music for it.
