If you are someone who missed the Chennai Express trailer then you don't know how badly Deepika Padukone has impersonated a Tamilian. The clothes, the bling, the mannerisms... but that's another story.
For our present purpose let's stick to the nasal twang and, for want of a better word, bad accent. One reaction on Twitter: @VellaDev writes, "Her nasal voice & accent is irritating."
We asked several people in our office, who call south of India home, not one said the accent was even in the vicinity of bang on.
Interestingly, Deepika is not the only one to get her accent wrong. There are quite a few A-listers in the film industry who have failed to hit the right note with a language not one's own.
Aishwarya Rai did not get her Urdu right in Umrao Jaan (2006). Her words were too flat in the film for a sophisticated language like Urdu.
Kajol in Kabhi Khushi Kabhi Gham (2001) was way over the top and got her Punjabi accent all muddled.
Mithun Chakroborty got his Yumms (M) and Yeahs (A) a tad bit over stressed as a south Indian in Amitabh Bachchan-starrer Agneepath (1990).
Shah Rukh Khan played a south Indian in his ambitious movie Ra.One (2011). The king Khan, however, could not get the accent right.
People who got it reasonably right
Amitabh Bachchan is undoubtedly one of the few masters of languages and accents in Bollywood. Hailing from Allahabad, Uttar Pradesh, the actor has tried hand at several languages- Punjabi, Bengali, Awadhi, Marathi, and Bhojpuri. One of the recent examples is Sujoy Ghosh's Kahaani (2012) for which he sang Tagore's Ekla Cholo Re with reasonable success.
Boasting of Hyderabadi-origin, actress Tabu effortlessly aced the Bengali language in Gautam Ghosh's 2003 film Abar Aranye.
Bengali actor Prosenjit Chatterjee speaks flawless Hindi in Dibakar Banerjee's Shanghai (2012).
Hailing from Gwalior, Madhya Pradesh, Piyush Mishra is another actor who cab under the skin of the character he is portraying. He effortlessly speaks Bihari Hindi in Anurag Kashyap's much-acclaimed Gangs of Wasseypur. Mishra alao spoke chaste Rajasthani in Gulaal as the younger brother of Dukkey Banna.
