Hear the word 'perfectionist' and the first name that comes to your mind is Aamir Khan. The actor makes sure to get into the skin of the character in his films. Also. he pays special attention to his physical transformation.
For every film, he changes his body type. He gains or loses weight for his character, depending on what the script demands.
For Rajkumar Hirani's 'PK', he gained 22 kgs for his role whereas, he built 8 pack abs and had an extremely muscular body for 'Ghajini'. The actor sported a mean look for '3 Idiots' where he played a student. Now, he is currently weighing 90 kgs for his upcoming film 'Dangal' where, he will be seen essaying the role of a wrestler,
He has been constantly moulding his body as per his role for his films. It is quite astounding yet, interesting to note the pattern of changes, Aamir went through all these years.
