Parineeti in 'Hasee Toh Phasee'
Parineeti Chopra, who plays a mad scientist in 'Hasee Toh Phasee', said: "It was quite difficult to play the role of a scientist in 'Hasee Toh Phasee'. There was no reference point for me. No actress in the industry has ever attempted to do a role like this because in our industry either the female characters are normal or mentally challenged. My role is a cross between the two."
