Aamir Khan has yet again displayed his perfectionist streak! He managed to convince the makers of Ghajini to make a quick trip to South Africa for shooting just a four minute song.

A source tells us, "Aamir was shooting in South Africa a few months back for some important scenes and a duet number.

But during the shooting of action scenes, Aamir encountered a leg injury and he had to rush back to India. The duet number which was to be shot on him and debutante Asin was left to be picturised.

But then after Aamir got back in shape he expressed his wish to the makers that they should again go back to South Africa to shoot the pending duet.

By then almost the entire shoot of the film was over. But since Aamir insisted the producers were left with no choice but take the crew to South Africa in a special chartered flight."

"Aamir is known for his secrecy concerning plots of his films and his character but this time he made a limit by even keeping the shooting location of the film a secret for the crew members right till they reached South Africa.

Everything was kept hush hush and even after shooting the song the crew members were told not to disclose anything." the source adds.

"Ghajini's director, AR Murugadoss was a bit hesitant initially as it would escalate the cost but Aamir convinced him that he wanted nothing but the best for the film and for that reason alone, the director had no choice but to relent." concludes the source.

Ghajini starring Aamir Khan, Asin, Jiah Ali Khan and Pradeep Singh Rawat is releasing on December 25th worldwide with over 1500 prints.
