The 29-year-old ABCD 2 star has changed his gym regime to beef up for the role. He shared a picture of his new bulked up look on Instagram.
"#badrinathkidhulaniya. Needed to change my training for the role. Changing training methods keeps gym workouts very interesting," he wrote in the caption.
Varun was also seen donning a tattoo of 'Badrinath' on his hand at several events he attended in last few days.
To be directed by Shashank Khaitan, the movie stars Alia Bhatt playing the female lead.
Varun and Alia appeared together two years ago in Humpty Sharma Ki Dulhania. The film is being touted as the next in the "Dulhania" franchise.
The actor will next be seen in action-adventure film Dishoom, directed by his brother Rohit Dhawan. John Abraham and Jacqueline Fernandez are also part of the film.
