i would say mega prostitute sunny leone is the biggest female actress of modern age..... adjusted for screens and ticket prices and opening collection of her movies would reach like 15cr today....... that is equivalent to akshay kumar in his peak.
even madhuri digzit was at her peak when she was playing a prostitute..... like in khalnayak.... side note....madhuri dixit was obsessed with playing prostitute on screens..... my favorite is obviously from devdas...
side side note...i wonder why every actress in her peak chooses to play a prostitute.... that old time woman PAKEEZA...... to these new ones.....like kareena kapoor in chameli .or aishwarya in umrao jaan....... or katrina kaif in TOH.... or that auty ...ummmmmm kya naam hai...... that producer wife..... she was in dirty picture..... begam jaan.
