We can be made from addition or subtraction
Our best are often a popular attraction
Some you can touch,
and some you cannot
One with a dozen will heal you
Another, inumerable, shan't be bought
Some of us have thousands, and some, just a few
We all can change one's point of view
But, y'know, sometimes words have two meanings
Most of us have utility
but others are for show
Like one befuddling, three worlds all in one
made 'round sixty years ago
By now you may have guessed what we are
so we ask that you find our brother, a movie star
He watched a broken man escape from prison
who let fear find him, and now is risen.
This riddle follows a similar format to my most recent riddle. About half of the lines describe the group itself, and the other half make various cultural references to famous members of this group. The accepted answer will explain at least three of the cultural references described, as well as the identity of the famous brother from the final stanza.
For the first line, I'll elaborate:
These things used to be made using "subtraction", but now, almost all are made from "addition".
The second line:
Take this line literally. Some of these things are uninteresting, but others are very popular.
The second stanza:
The answer (for the group's name) is a word which is used literally ("can touch") or figuratively ("some you cannot")
The last two lines of the second stanza describe "some you cannot" touch.
The third stanza:
This contains true statements regarding this group of things, as well as a cultural reference shared with another stanza.
The fourth stanza:
The "one befuddling", made "for show" (not "utility") was made in the 1950s.
The fifth/sixth stanzas:
The brother is in a movie but is not acknowledged in the credits.
The word "watched" was chosen for a reason. This rules out Bane and Bruce Wayne as correct responses.
