I'm a little stuck... Click here to teach me more about this clue!

'leading man' is the definition.
(eg the hero of a film)

I don't understand the rest of the clue.

(Other definitions for hero that I've seen before include "Lover of Leander" , "Courageous man" , "Idol" , "Man of great courage and deeds" , "paragon" .)

I've seen this clue in The Independent.
