After Lara Dutta and Katrina Kaif,who learnt underwater stunts for their roles in Blue and Zindagi Milegi Na Dobaara,respectively,it is now Bipasha Basus turn to dive into the water. The actress,who is reportedly playing a drug addict in her forthcoming film Dum Maro Dum,is training in the underwater routine. This will be the first time that the actress is going underwater for a film. I attended a few classes and then I had to stop as I was busy with some work,and now it’s back to the sessions. Once I complete my training only a few days of shooting will be left to complete my part, said the actress. Dum Maro Dum is directed by Rohan Sippy and also stars Abhishek Bachchan,Rana Daggubati and Pratik Babbar and is based on the drug scenario in Goa.
