Hero in a Box

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)

Now do you remember him? He was recently in Juno, playing her dad and Spiderman playing the head of "The Daily Bugle".
