The 39-year-old actor tweeted a picture of himself coping the iconic style of the late actor and wrote, "The Rajesh Khanna fan # Sarbjit #Punjab #hopelessromantics."
The upcoming biopic will see Aishwarya Rai Bachchan essaying the role of Sarabjit's sister, Dalbir Kaur in the film and her look is de-glammed with minimum makeup.
The film, which is being helmed by filmmaker Omung Kumar, is slated to hit the theatres on May 20.
