This page needs some clean-up. A lot of the examples (maybe most of them) are of characters who are often, but not exclusively, referred to as something other than their real name. There are two problems: (1) the idea of this trope is that they are only called by their descriptor or job title; and (2) many of the appellations listed are just nicknames, which would place them under "Only Known by Their Nickname," not this trope.
To cite one offending example as illustrative of the problem, the entry for Hocus Pocus remarks that the character Max is addressed by bullies as "Hollywood" because he came from Southern California. All the other characters in the movie call him by his real name, and furthermore, "Hollywood" is not a job title or a descriptor of what Max does, which is what the trope description calls for.
There are many such examples.
Just a warning: looks live Film-Live Action is bleeding into Live Action TV. There are examples from The Fugitive and La Femme Nikita just at a glance.
No matter what I say there is a 40% percent chance I'm not being serious, and if I sound like I'm not then I probably am.
I have a real life example of this. On my fire station we have a red head who we obviously called Ginger, and only called him Ginger. The annual banquet comes around and the Chief reads off a list of members that have finish their training and are now full members, and referred to him by his real name. What followed was a collective"who?" and a very awkward pause followed by "Oh you mean Ginger" funny as hell in retrospect
This list appears to have entries which don't match the trope.
To the best of my understanding, in order to match the trope, the person needs to fill the following requiremrnts: 1. The character is presumed to have a real name, although usually we don't know it. 2. The character is generally refered by a nickname in other characters' speach. 3. The nickname is related to the person's job or role in society.
