A combination of Captain Ersatz
and Adam Westing
. When An actor or actress doesn't really play themselves but play a Captain Ersatz
of themselves, I mainly propose this as a sub trope of both. I am also proposing this so people don't have to dig through the above categories to find specific examples of this.
Examples include Billy Ray Cyrus as Robby Ray Stewart on Hannah Montana and some may argue Lindsay Lohan plays a parody of herself in Machette.
