Directed by Prem Soni, Ishkq in Paris is a passionate love story set against the backdrop of the Parisian fashion world.
A source told The Times of India: "Preity and Prem sent Isabelle the script a few months ago. Within days they got an email from her saying she loved the script, and could meet them in Paris to discuss the details. Isabelle plays the narrator in the film, who introduces the characters and the city of Paris.
"After Isabelle agreed to be part of the cast, she started learning Hindi as she will speak a mix of both Hindi and French in the film. She is working on her accent and the finer nuances of the language. She starts shooting on December 12."
The source added: "Preity is also learning French as she will speak a smattering of it in the film."
Prem Soni said that he is happy to be working with an award-winning actress like Adjani.
"Isabelle is one of my favourite actors," he said. "It will be special to direct one of finest actors in the West. It's indeed a very big thing for me! This is the first time that an international actor will be speaking our language so fluently in a Hindi film."
