Mumbai: Actress Asin Thottumkal, a trained Bharatnatyam dancer, especially learnt waltz for an advertisement shoot.
A sequence in the ad of a soap brand endorsed by Asin required her to perform the ballroom dance of the style `Viennese waltz` and she picked up the steps in a short while.
Asin, who was shooting in Wai for "Bol Bachchan" at the same time, had to juggle between both these professional commitments.
After the film shooting when everyone would call it a day, Asin would learn waltz during the nights.
According to a source close to Asin, the actress is mesmerised by this western dance form and is planning to pursue it further as and when she wraps up the shooting of her movies.
