Amir Khan had to eat over 1000 paans for PK

Aamir Khan will be seen in nine different avatars and during the course of the film, the actor had to eat over 1000 paans. "In real life paan is not a habit, I have it once in a while but for this film I chew paan for every scene. I would at times eat about 100 paans in a day. We had a paanwala on the sets," said Aamir Khan in a TOI report. Apparently, for every take, Aamir had to eat a fresh paan to fill his mouth, also before beginning the shoot Aamir would eat at least 10-15 paans to get the right colour inside his mouth and on his lips.
