Quoted from Frippertron:The point of the thread is to think of awesome comic themes from the smaller publishers that would make great pins. Nobody is delusional enough to think they will actually be made. It's just fun spitballing. Although at one time a Hellboy pin coulda and shoulda been made!
I think the point kirkgun makes is that they could be made if a movie brings them mainstream. Deadpool and Guardians of the Galaxy are examples of characters that would not have gotten a pin if it weren't for the movies. Spawn, The Crow and Hellboy are getting reboots. If they sell enough tickets at the box office, then it shows the character is mainstream enough.
Men In Black would be a good theme, I'm surprised that hasn't been utilized yet.
Many, Many great books mentioned, but they do not have a big enough following.
