Director Ayan Mukerji,who is currently working on the post production of his soon to release Yeh Jawani Hai Deewani landed at Wai on the sets of Chennai Express a few weeks ago. The director wanted Deepika Padukone,who was shooting there,to dub a few lines for the trailer of Yeh Jawani Hai Deewani. But to his dismay he realized that there was no suitable infrastructure around. Shah Rukh Khan offered Ayan and team,his luxurious makeup van that has one of the best sound systems to for dubbing. In fact Shah Rukh Khan not only allowed Ayan and his team to use his van for dubbing,but also ensured that the Yeh Jawani Hai Deewani team get a good lunch and offered them recreational facilities as they had driven seven hours at a stretch to reach the sets.
