I have decided to base my Hero in a Box on 'character actors'. Here is the definition from
http://www.dictionary.reference.com/ :
noun
an actor who specializes in playing supporting roles
It also states on Wikepedia(
http://en.wikipedia.org/wiki/Character_actor ) that character actors usually 'play a particular type of role'It also says that: ' Some character actors have eventually gained star status and have become widely known, or perhaps even become lead actors'.
Ex: Johnny Depp, Dustin Hoffman, Gary Oldman and Leonardo DiCaprio.
TIME even did a photo essay on character actors :
http://www.time.com/time/photoessays/2006/in_character/You may recognize some of them from popular movies like 'Spiderman' and 'Back to the Future'.
For me, I hear the name and I have no idea who this person is and then I see a picture and I remember.
For example, have you ever heard of J.K. Simmons? No? (click on the link)
