Shatnerian Persona

right|300pxThe Shatnerian Persona, named for Canadian actor William Shatner, is the title of an academic paper that Phil Howell didn't bother to write. In it, he details the phenomena of actors who could be considered to be "dudes" who pretty much play themselves in any role they are given, however disparate the roles themselves. Examples include Shatner, Christopher Walken, Adam West, and Dave White, assuming that Dave White was ever in a movie, which he really should be.
