The only problem was that the water in that particular locality was highly dense and infected! The locals too swear by not going inside the water and if done, then they need to get vaccinated immediately.
The scene requirement was such that the boys had to be shown coming out of the water. Director Indra Kumar did not want to risk getting the actors skins exposed to that water. The solution- The crew arranged for a large amount of bottled mineral water!
But what began as splashing water over each other to prepare for the shot, slowly turned into a riot of sorts as the actors, who are very close friends in reality, got into a mischievous mood & began throwing water over each other! "It was a sort of a mini Holi sans the colours" reveals a source from the sets.
Well, if you have such a mad star cast, some 'Dhamaal' is surely expected on the sets!
