Shah Rukh and Ash sizzled on screen as a twin brother-sister jodi in ‘Josh’.Then their pairing was accepted in Aditya Chopra’s ‘Mohabbatein’ and Sanjay Leela Bhansali’s ‘Devdas’ too. They really had good chemistry.But that was that. They were not supposed to act together after that.It all started when Ash’s ex boyfriend barged into the sets of ‘Chalte Chalte’ and Ash ended up being chucked out in favor of Rani Mukerji.Ash never warmed up to SRK and Rani after that. Things soured badly between Sallu and her too.She moved on happily with the Bachchans, some international films and let her chemistry work better with Hrithik Roshan.Recently Mani Ratnam wanted to cast Shahrukh in the lead role opposite Ash in his latest bilingual film ‘Ravana’ which he’s working on currently.Now after things didn’t work out for him in Raju Hirani’s ‘3 Idiots’ and Shankar’s ‘Robot’, he seemed to have some free time.Mani had then spoken to him about ‘Ravana’ and the superstar expressed interest in the project. He wanted a good film in his kitty and didn’t care so much about the fact that Ash was the leading lady.But before Mani could come to Mumbai and give him a detailed script narration, Aditya Chopra approached SRK for his comeback film ‘Rab Ne Bana Di Jodi’.And the actor gave his dates to his dear friend.Mani didn’t want to delay the film and he took Abhishek Bachchan as the film’s male lead instead of SRK.So SRK and Ash lost a chance to work together again. Not that they mind, but maybe their pairing would have worked wonders for their careers. And maybe it’s a chance lost! .
