what acting really means

One of the slides in a Rediff special on Ms Rai-soon-to-be-Bachchan's pirouetting projects offers insight into what is widely regarded as acting in mainstream cinema:

Nimbooda (Hum Dil De Chuke Sanam)

One of the most breathtaking features of Sanjay Leela Bhansali's opulent love triangle were its song and dance sequences.

Aishwarya's animated thumkas, particularly, stood out in the fast-paced Nimbooda.

Reportedly, all the rigorous dancing steps gave Ash a bad case of sore feet. But the professional refused to take any breaks.

Her efforts were suitably rewarded with a Best Actress Filmfare award.

In summary, rigorous dancing constitutes acting. That has to explain (to such extent) why she snagged a Filmfare nomination for Best Actress for Dhoom 2 [a sample of whose writing was explored hereabouts]. Truly crazy kiyaa re.
