Wiki:

Walter Plinge is a pseudonym, traditionally used in London theatres when a part has not been cast, an actor is playing two parts or an actor does not want his or her name in the programme. Plinge was supposedly a real London pub owner, honoured by a group of actors with the borrowing of his name.

The name has also been used occasionally in American theatre, as has the more popular George Spelvin. Similar pseudonyms are David Agnew at the BBC and Alan Smithee in Hollywood.
