Aditya has been constantly changing decisions on the cast and the crew of his upcoming trilogy (if it can be called so) Dhoom 3. But one thing was fixed that after Sanjay Gadhvi deciding to part ways with Yash Raj Films, Aditya himself will be directing the movie but now even that remains under thought. Aditya is now thinking of giving the project to Scriptwriter Vikram Krishna Acharya. Dhoom 3 will be Vikram’s directorial debut. Acharya wrote the screenplay and dialogue of both Dhoom versions and the dialogue for Pyaar Ke Side Effects and Guru, and is writing the script for Dhoom 3 as well. Chopra plans to start filming towards the second half of the year, around the time that Gadhvi starts filming his first movie outside Yashraj, for Shree Ashtavinayak Cine Vision. That’s not all… And he has planned a casting coup with Shah Rukh Khan (in a negative role) and Aamir Khan hot on his heels as the policeman. What’s more, Hrithik Roshan will also be a part of the project, insists the source, although he may not have a fullfledged role. “Adi wants to make it a multi-starrer. It all depends on how the script shapes up but he’s definitely keen on pairing both the Khans together for the first time and also Hrithik Roshan,” says the source. Lagta hai ladai badi dhoom se hone wali hai!!!
