Mr Perfectionist was apparently on medication while shooting for Dhoom:3
We have heard that Aamir Khan while shooting for Dhoom:3 song, Malang had to be on medication to keep nausea down for a few days. The song has been shot at a height of about 80 feet and Aamir had to rotate 60 times in a minute for the same. Since Aamir plays the role of a gymnast in Dhoom;3, so he was required to do this. However, the perfectionist that he is, the actor willingly took it up without complaints and wanted to do it just the right way.
It took the team about 15 days to complete the shoot of the song and Aamir Khan was on medication for those many days. The medication was to help him keep nausea down. As he was at such a height, taking turns, it is human to feel nauseated. Also to make sure all is well, the makers of the movie specially called a doctor, who works with gymnasts, to be on the sets to help Aamir.
