"I am working on Prabhu Deva's film. It is a love story," Poonam told.
The 50-year-old, who has a son and daughter, says she is now more open to doing films as her kids have grown up.
"I will be doing one or two more films since my kids are all grown up now and I can concentrate on films again," added the actress, last seen in 2011 film "Miley - Naa Miley - Hum".
Prabhu Deva's film should be out in another "two to three months", she said.
The film is reportedly a remake of Prabhu Deva's Telugu blockbuster "Nuwostananante Nenodattana", which was earlier remade in Tamil as "Unakkum Enakkum".
