That he gets to know co-star Asin better before shooting a romantic song together

Aamir Khan had to shoot a romantic song with Asin for Ghajini. The two actors have never worked together before and Aamir realised that they needed to share a comfort factor before shooting for the love song.
Khan decided to get to know the South actress, to ensure there was no awkwardness between them.

Experienced

Says a source close to Khan, "Aamir is an experienced actor and can switch on and off at will but he realised that Asin might not be ready to break into a romantic number at will. They needed to establish a rapport. Four days before shooting, were kept aside for Aamir to get to know his leading lady and put her at ease, so that the romantic song would look natural. Aamir and Asin would go for long walks in the desert. Nobody knew what they spoke about but one could see Asin gradually relaxing and becoming comfortable with Aamir. And that's the reason the blazing chemistry on screen."

Though Aamir and Asin had shot some scenes before, the song was the first romantic interaction.

Bare-bodied

The song was shot for in Namibia. Ahmed Khan has choreographed the Guzarish song while Manish Malhotra and Meghna Kapoor styled Asin. The source adds, "A charter aircraft comprising 23 people was taken to Namibia and the song was shot in 'dead man's land'. Sosusfei Lodge, where Aamir and the crew stayed is part of the dessert. The location was a two-and-a-half hour ride from the hotel. Aamir was very particular about his workouts as he had to shoot his bare-bodied sequences there especially for the song so a makeshift gym was created at the base camp of the shooting locations."
Ghajini director, AR Murugadoss, says, "We all landed in Namibia to shoot this song and this was the first romantic song between the two. Aamir is an experienced actor and he had genuinely liked Asin's performance in the Tamil version of the film. He praised her performance giving Asin a lot of confidence."
