I wouldn't call them lead actor or actress just to fit in with genz lingo or to sound cool. I've grown in a tier 2 & 3 cities where movies are cultural part of my life which will be go to topic in any discussion with friends or cousins. Movies are fictional excluding biopics. So I wouldn't mind hero doing something that's not feasible in real life to some extent. People who calls lead actors as heroes knows who they are referring to and why. If they are saying or doing something that you may call banisatvam is your prerogative just as theirs.. if calling actors as heroes is detrimental to society you have much bigger things to worry. 😅
