Now KJO as a wife-beating sex maniac in Saat Khoon Maaf was an inspired choice and would have been great piece of casting. I am sure it would have earned Karan Johar a zillion brownie points and weirdly would have dampened the whispers about his 'leanings'.
Of course, Karan Johar can't even fathom the concept of such characters, forget embodying them. The guy thinks "My Name is Khan" was a massive creative leap for him! The frog in the gilded well is now a Director in Bollywood.
