Actors transforming themselves to get into a particular character is nothing new, nor is making a biopic an unusual affair in Bollywood. But, what's new is how seriously Bollywood is taking its transformation game these days. 

In fact, with Anupam Kher as former prime minister Dr Manmohan Singh and Nawazuddin Siddiqui as Bal Thackray, we've already seen what actors and filmmakers are capable of pulling off.

Now, a new name is making rounds for his incredible transformation, and we're not talking about Vivek Oberoi. We're talking about the national heartthrob, R. Madhavan who shed his cool dude avatar to get into the shoes of ISRO scientist, Nambi Narayanan.

The 48-year-old actor not only looks unrecognisable but legit looks like Narayanan's doppelganger.

In case, you haven't been following the actor on social media, Madhavan is currently working on his debut directorial 'Rocketry: The Nambi Effect', a biopic on the scientist and aerospace engineer. It took him 14 hours to get the look and nearly two and a half years to get into the character and learn how to walk and talk like him.

Madhavan looks so convincing in these pictures, that sometimes it got difficult to identify which of them is the real scientist and who is his on-screen avatar.
