Mumbai -- Action hero Sanjay Dutt who delivered powerful performances in movies like Khalnayak, Vaastav and Dus said he was upset to know about the failure of action movies at the box-office. During late 80s and early-90s actors such as Ajay Devgn, Jackie Shroff, Akshay Kumar and Sunny Deol were famous for their performances, but later on comedy movies took centrestage. "There was a time when Ajay, Akshay, Jackie, Sunny and me all were called action heroes and we lived in that era for a long time. And suddenly for us there was a period of no action ...only comedy films were working. I was taken aback. It was surprising at that time," said Sanjay, who explored action with 'Vijeta' 'Taaqatwar', 'Kabzaa', and 'Hathyar', among others. "That time I used to talk to Jackie, Sunny or Ajay and we all used to wonder where action has gone. I am happy that it has come back and that is what we are. The best part is that South cinema never forgot that (action). That is the reason South films are larger than life...people have fans," Dutt said.
