Nadiadwala is also in talks with actor-turned-politician Arnold Schwarzenegger for the film that revolves around Akshay's character, a stuntman in Hollywood.
'Believe me, meeting Arnold for a role is easier than meeting some of our stars in Bollywood. In a way Arnold is our host in California since he's the governor. Access to the Governor House is easy. Arnold and the city are very welcoming, ' Nadiadwala told.
'I'm leaving for my final talks with Arnold. Since he is a politician, we can't just fling his name around. We've also finalised Brandon Routh, who played the latest 'Superman'. And we also have the 'Terminator' heroine Linda Hamilton in 'Kambhakt Ishq'. We expect to sign all three by early next week, ' he added.
While some of the Hollywood actors have walk-on parts, Denise Richards has a far more substantial role.
'Denise plays Kareena's rival in love and has lots of romantic scenes with Akshay and Kareena. We also have several other Hollywood actors, about a dozen, who'll do walk-on parts. Those we won't like to publicise.'
Nadiadwala, however, did have some trouble signing these Hollywood icons.
'But only because of the fiscal conversion. I'm still getting used to converting rupees into dollars. Nowadays I'm only talking dollars. As a producer these stars are expensive. But as their fan I feel money is of no consequence.
'The important thing is we aren't bringing Hollywood stars into 'Kambhakt Ishq' as a gimmick. Our hero is a stuntman in Hollywood. So the stars all fit into the plot.'
Nadiadwala, who shot his Salman Khan- and Akshay-starrer 'Jaan-e-Mann' in New York, will shoot 'Kambhakt Ishq' in Los Angeles.
'The US is very shooting-friendly. I shot my last film 'Jaan-e-Mann' in New York. That was as easy as shooting in our own Film City. In fact, Karan Johar recently shot in Miami and he says it was a pleasure.'
Nadiadwala starts shooting in LA from June 27.
'Then 20 days in Italy. The next five months will be gruelling. It's a 22-hour flight from Mumbai to LA, ' said Nadiadwala who was earlier planning to charter a plane to LA.
'But now it doesn't make financial sense. One of my units left a week ago. Kareena is joining us from London. Akshay is coming from the Bahamas. So no point in chartering a plane from Mumbai.'
The film might be dubbed into English for global audience.
