There was another scene, which had Vidya really worried. She had to slap Sanjay Dutt.
"I didn't know how I would do that," Vidya cries. "People took me for a royal ride because they told me that I would have to actually slap him. I started practicing on my assistant -- but I would lift my hand high to slap him and would come down really hard but would stop just near his face. Finally, I realised everyone was just pulling my leg. I didn't have to actually slap him; the trick camera did it."
The actress also got along famously with her other co-stars, Arshad Warsi and Boman Irani.
"I did not have any scenes with Arshad," she says, "But he is so talented and funny!"
She elaborates, "When we went to Goa for a song, we forgot it was a film shoot. We were splashing in the water, jiving, doing yoga..."
"And everyone wanted to know whether I was going to work with Dr Asthana (Boman's character in Munnabhai MBBS)," she continues. "They wanted me to bring back his laughter recorded! That's how popular he is."
In Lage Raho, Boman plays Lucky Singh, a rich builder, and Munna's 'dushman'.
Vidya concludes the interview with suspense, and refuses to reveal what role Gandhiji plays in the film. For those who don't know, Gandhi's image is flashed in the promos of Lage Raho, and for a while, the film was even titled Munnabhai Meets Gandhiji.
"Gandhiji and his ideologies play a very important part in the film," is all Vidya says, as she gets ready for the next interview.
