In Subhash Ghai’s Hero, the lead female character (played by Meenakshi Sheshadri) was a classical dancer. But Athiya Shetty’s character in the remake of the 1983 hit, is a lot different than Meenakshi’s. To begin with, she is a modern-day dancer who is proficient in contemporary and classical dance forms.
While the debutante is well-versed with the contemporary dance-style, the real challenge was to learn the classical moves. “I play a dancer in this film, just like Meenakshiji in the original. However, my character Radha, is an all-rounder. For a few sequences, I needed to look easy with classical dance as well, which is why I learnt the basics of Kathak,” said Athiya.
