In an industry where it is easy for stars to demand for body doubles, Ranbir Kapoor [ Images ] chose to perform his own stunts, something that he has never done before.

Sources reveal that in spite of having a water phobia, Ranbir performed an entire underwater sequence Pepsi The Game's Level I that goes on air this week on March 31.

The whole sequence took over 4-hours to shoot.

The actor did not let the production crew know about his phobia till after the sequence was completed.

While performing yet another tough sequence of climbing a high wall to pull out a few daggers, Ranbir hurt his hand, but went ahead and completed the shot.
