Though Deepika Padukone hails from South India, she isn't as well versed in Tamil as her native language. Moreover, though in CHENNAI EXPRESS she is shown as a Tamilian, her character is required to incorporate only the accent while speaking in Hindi. Once she began work on the film, it wasn't easy for her to begin with as the thin line between authenticity and humour had to be kept intact. This is where Shahrukh came to her rescue. ''Shahrukh could see that Deepika may struggle to get her accent right. In order to help her, he showed her a few videos on different ways that Tamil people speak in Hindi. He also pointed out that when that happens, the grammar changes a little bit as well.

Especially for those few South Indians who are not comfortable in Hindi, there are some apparent mistakes. Deepika could relate to this as well since she had moved from Bangalore to Mumbai a few years back and had to soon adapt to the Hindi flavour,'' informs our source. Says Deepika, ''Yes, this had happened with me in real life. I used to mess up on grammar in my earlier days. Shahrukh was a good help though during the making of CHENNAI EXPRESS. His guidance helped me. After that I didn't have to rehearse. I went on the shoot, said my first dialogue and it all became a part of me. Today you can give me any dialogue in Hindi and I will speak it in true Tamil accent.''
