Bachchan Jr. has ditched close friend Apoorva Lakhia (of Shootout at Lokahndwala fame) at the very last minute for his next project – Mission Istanbul. Why, you ask? Well the other male lead in Mission Istanbul is Vivek Oberoi who as you may remember shares a public past with Abhishek's wife - Aishwarya Rai. At one point Ash had gone running from Salman's bulky biceps to Vivek arms! And it seems Aby Baby is worried about things getting complicated (or maybe he simply thinks vivek might get more accolades considering he IS the better actor!) although Lakhia has promised that neither of the boys would come together in a single frame and to help make things better for his mate, he even kills Vivek's character by the time you will head for popcorn during the interval. So as Lakhia is busy finalizing locales in Istanbul to shoot his movie it seems he first has a mission to find a missing male lead for his film!
