The filmmaker, who is working with the actress for the first time, said: "Tabu is a legend in her own way. It was great working with her."
He has finished shooting and said the film will come out in January next year.
"I am almost done with my next film 'David'. The film is in its post-production stage and I am very much happy with the film. The film is slated for January 2013 release," Nambiar told.
"The film was simultaneously made in Tamil and Hindi and it will be dubbed in Telugu," he added.
The cast of the film has names like Neil Nitin Mukesh, Vinay Virmani, Monica Dogra, Isha Sharvani and southern star Vikram.
A gangster-comedy, "David" was shot in Mangalore and Mumbai, among other locations.
Nambiar said: "I can't reveal the storyline of the film. All I can say is Vikram, Neil and Vinay are playing David in the film."
