Mumbai, Nov 5 (IANS) In a role reversal of sorts, Bollywood actor Abhishek Bachchan needed to carry his father piggyback and trot across a vast field for a sequence in 'Paa'. To the relief of director R. Balki, Abhishek simply breezed through the difficult scene.

'Abhishek did it in one take. He carried his father effortlessly across the vast field. We shot the sequence near Cambridge in England at a place called Bury St Edmunds,' Balki said.

The place was chosen not just for its green acres which facilitated Abhishek's run with his father on his back, but also to avoid large crowds of gawking Indians. On asked how he felt to be carried by his own son, the Big B quipped: 'Carrying me piggyback was Abhishek's job. Jaya and I merely produced a strong boy!'

'The most tedious part of playing the 12-year-old boy in 'Paa' was the makeup. I had to sit still for four-five hours every morning without moving, eating or even drinking water. For a sunrise shot I had to be up from 11 p.m. the previous night doing the makeup to be able to shoot on time the next morning,' he added.
