They say 'Friends in need are friends indeed', and this saying was proved true by filmmaker Ayan Mukerji, who helped his close buddy Ranbir Kapoor to perform a few scenes in their forthcoming film 'Yeh Jawaani Hai Deewani'.

According to sources close to the production, Ranbir has a fear of heights and water. Hence, when he was required to perform scenes that included those elements, Ayan ensured that Ranbir felt comfortable.

There were certain scenes that initially sent chills down Ranbir's spine. From sitting on the edge of a tall building, screaming from ice-covered mountains, to taking a dip in the deep seas, Ranbir had reservations on doing these stunts.

Ayan, who was well aware of the fact that these scenes would not come naturally to Ranbir given his fear, helped the actor perform the stunts by enacting them all before he did.

Ayan jumped into the ocean, sat on the building edge and even climbed the mountain top before Ranbir had to do it all. And only when Ranbir reached his mental comfort zone to perform these stunts, Ayan shot these scenes.

Thanks to Ayan, Ranbir's fans will get to see their star perform these stunts, which would certainly be a treat for them.
