Aamir Khan starrer "Fanaa" clocked 10 years of its release on Thursday, and director Kunal Kohli took the chance to share some anecdotes from the film's making.

"10 Years Of 'Fanaa'. The original script by Shibani Bhatija didn't have Rehan Aamir Khan saying shairi, I got it in while writing the dialogues," Kohli tweeted on Thursday.

The director also said that Aamir had only heard two narrations of the film to say "yes".

It was the "Ghulam" star, who suggested that Kajol should play Zooni's character in the film.

"When Adi chopra and me asked Aamir Khan, which three girls do you think are best suited to play Zooni in 'Fanaa'. His reply: Kajol, Kajol and Kajol," he wrote.

The director also wrote that the song "Mere haath mein" had to be reshot due to the cold conditions in Poland.

"'Fanaa': due to the cold in Poland, Aamir Khan was in so many layers we had to reshoot 'Mere haath mein' on a set. Though I liked the original better," he tweeted.
