Bollywood body transformations: From Kartik Aaryan’s Dr Freddy to Shah Rukh Khan in 'Pathaan' '', see 12 make-overs you’ll need to see to believe

How far would you go for a job? For actors aiming to get into a character’s skin, it requires grit, gumption – and perhaps a little bit of help from the make-up guy. Here’s a look at some on-screen artists who took their transformations to the next level.

Vivek Oberoi is the latest actor to take his character makeover to the next level. For his upcoming OTT release 'Dharavi Bank', Oberoi put on 10 kilos, which he did with a combination of the right diet and right exercise. IANS reported that the actor said, "I started much ahead in time, following a well charted out regime. We took references from real life cops. While drama is integral to the show, we wanted the look and feel to be as real and believable as possible. A well balanced meal, as prescribed by my nutritionist was the starting point. It was a healthy combination of carbs with protein." On the workout front, he went all out with cardio and weight training in equal parts. "I had to look big but also have the agility, which we achieved successfully," he added. Directed by Samit Kakkad, the series will premiere on November 19 on MX Player.

Recently, Kartik Aaryan joined the list of celebrities who underwent a drastic physical transformation for his role. For the role of Dr Freddy Ginwala, Aaryan did a complete 360 from his last role as Rooh Baba, piling on 14 kilos. The actor worked with celebrity fitness trainer Samir Jaura, who revealed that putting on weight was difficult since the star was physically predisposed to having a lean figure. He said, “He was able to achieve the look well in time, following disciplined routine workouts and the right diet plan.” The trainer also commended Aaryan’s dedication.

Shah Rukh Khan will be seen next in Pathaan after a short hiatus. The 57-year-old was pictured sporting eight-pack abs for his role - a result of four years of hard work according to his personal trainer. Prashant Subhash Sawant told Indian Express that Khan has been hard at work for his chiseled look in the upcoming release.

Ranveer Singh in ‘Padmaavat’. National Award-winning Indian make up artist Preetisheel Singh was in charge of creating the characters of ‘Padmaavat’, a sweeping fantasy film directed by Sanjay Leela Bhansali. “When working with Bhansali Sir, one has to be ready to always put in that extra bit as he has such a keen eye for aesthetics and detail. I read the script and understood the characters — how they dealt with people. Visualised the environment they would have grown up in, their likes and dislikes, their personality et cetera,” said Singh in an earlier interview with KoiMoi.

Rajkummar Rao in ‘Raabta’. Indian make artist Zuby Johal, who has worked in films such as fantasy horror ‘Tummbad’, was on call to transform Rao as a 324-year-old man. ‘Raabta’, starring Kriti Sanon and the late actor Sushant Singh Rajput, wasn’t well-received, but Rao’s role didn’t go unnoticed.

Amitabh Bachchan in ‘Paa’. The legendary actor played Auro, a child battling the rapid-ageing disease Progeria. International make-up artists Christien Tinsley, whose credits include ‘Passion of the Christ’) and Dominie Till of ‘Lord of the Rings’ fame) worked on Bachchan.
