The Troy McClure Character half mask was created for Washburn’s Mr. Burns, a Post Electric Play. He appears in the second act. This mask was designed as a prince of sorts which is appropriate since Troy is a washed up B list movie actor that has seen better days.
The character of McClure fulfills the archetype of the has-been egotist. Every community has this person at work, in the community theatre, waiting tables or working at the local convenience store. We empathize since we have all seen better days.
The comic convention of the has been as a character is lovely since it provides for a character that is in a constant effort to recreate the past, be more than or prove worth. The outcome is always the same. Failure. Its just that the has-been doesn’t recognize the failure.
