Bharat Bhushan
Any one saw Mirza Ghalib? Or Baiju Bawra? My God! Films on such great personalities had cast the effeminate Bharat Bhushan as the eponymous character. This man was the ‘T” in the word TERRIBLE.
Pradeep Kumar
Raat Aur Din had the sublime Nargis enacting a difficult role with élan so one hardly noticed Pradeep Kumar, the most wooden actor ever. But it was in the musical Taj Mahal that his real ‘talent’ was exposed. At times he was also known as Pradeep Kumar Lakdawala or Pradeep Kumar Furniturewala.
Sanjeev Kumar
He was the king at hamming. He would contort the upper portion of his face and make a very funny noise while doing emotional and dramatic scenes in movies where he would wear a wig. I think he is one of the most overrated actors in the Hindi film industry. He was okay in films like Angoor, Koshish, Pati Patni Aur Woh, Mausam but pathetically funny in Khilona, Sholay, Vidhaata, Khuddar, Qatil, Naya Din Nayee Raat and many many more.
Amol Palekar
He was good in the movies of Hrishikesh Mukherjee and Basu Chatterjee but otherwise he was mediocre and even corny. Same muddled expressions even while playing a villain.
Aamir Khan
People are going to kill me. This man is overrated. And boy how much is he overrated! Same expressions, same dialogue delivery and same body language. See QSQT, see Dil, see Lagaan and see Dil Chahta Hai.
