After the tremendous success of his latest movie ‘Cocktail’, which also starred Deepika Padukone and Diana Penty, actor Saif Ali Khan has started planning his next home production, which will be a romantic movie.

And this time the actor is thinking of casting none other than Hollywood star and Academy Award winning actress Natalie Portman.

“A love story we are working on ... It’s a secret ... We are doing a film with Natalie Portman,” said the actor to a daily.

The actor, who is 41 years old, said that there were no age restrictions when it came to love and hoped that he would be doing romantic movies even when he is 50.

“I hope I can do romantic films at the age of 50. There is no age for romance. If the story is nice and the character suits you then why not do it. It is not like you can do only action films at a certain age. As long as you look good doing the part, there should not be any problem,” he said.

When asked who were the Bollywood actresses he wished to work with Saif Ali Khan named Katrina Kaif and Priyanka as actresses on top of his wish list.

“I really want to work with Priyanka Chopra and Katrina Kaif. Though I did work with Kat in Race, I, however, don't think she considers it her work. At the time, she was still finding her feet in the industry,” he concluded.

This wont be the first time that Natalie Portman would be seen opposite a Bollywood star as the actress has already worked with Irrfan in the 2009 ensemble flick, New York, I Love You.
