Here goes. This is simple:
1) Amitabh Bachchan for Deewaar, Sholay, Mili, Namak Haraam, Amar Akbar Anthony and Bemisal.
2) Sanjeev Kumar for Angoor, Sholay
3) Aamir Khan for Lagaan, Jo Jeeta Wohi Sikandar, Rangeela, 3 Idiots, Ghazini, Ghulam
4) Nana Patekar for Ankush, Prahaar, Thodasa Rumani Ho Jaye
5) Naseeruddin Shah for Jaane Bhi Do Yaaron, Drishti, Mirch Masala
6) Om Puri for Ardh Satya
7) Ajay Devgan for Omkara, Company, Bhagat Singh, Rajneeti, One Upon a Time in Mumbai
8) Anu Kapoor for Arjun, Droh Kaal
9) Anupam Kher for Saaransh
10) Rajesh Khanna in Anand, Namak Haraam ties with Dharmendra in Chupke Chupke
Of the current lot, I can't find any notable performers. Maybe because they are not challenging themselves enough. Shah Rukh Khan came close with My Name is Khan.
