Reportedly Akshay Kumar has opted out of the world's big show world tour that is schedule in 2008. Akshay was part of Bachchan's group called Unforgettable. The reason for his opting out is not just date problems but also that he doesn't get along with Amitabh Bachchan ater the   Bhool Bhulaiyaa   controversy. There are two groups in the world tour. While one is called Unforgettable, the other is Temptation. Unforgettable will feature Big B, Abhishek Bachchan, Aishwarya Rai, Lara Dutta, Riteish Deshmukh and Bipasha Basu. The Tempataion group will have stars like King Khan Shah Rukh, Preity Zinta, Rani Mukherjee and Priyanka Chopra.It is believed that both the tours will have separate schedules, and Temptation will set out before Unforgettable. A source informs that Akshay always had date problems as he is one of the busiest actors from the industry. In spite of that he was looking forward to the world tour's grand show. While reports initially stated that Akshay was asking for an exorbitant fee, reports now claim that he has 'date problems'.But it's more than that we say. It can be recalled that Amitabh was supposed to play the role played by Akshay Kumar in Bhool Bhulaiyaa . This annoyed Amitabh. Akshay and Bachchan were involved in a feud as to who would acquire the rights of the South film that was recently remade into Hindi (Bhool Bhulaiya). Akshay, Bachchan feels unfairly acquired the rights and decided not to work with him henceforth. Bachchan refused many films which starred Akshay in the lead, including Rohan Sippy's Nikhil Advani-directed Made In China . But the war doesn't end here.  Another issue could be 'ego-hassle'. Unforgettable is dominated by the Bachchans and after Ash-Abhishek's marriage this is going to be their first show together, and quite the USP of it all. This may just leave Akshay feeling shortchanged. However, hunk Khiladi is considering having his own show next year, and this one, too, will travel the world!
