New York Comic Con cosplay attendee in his costume, as The Red Knight, Worst Nightmare from the Robin Williams movie " The Fisher King".
Robin Williams portrays Parry, a former professor of medieval history, who lives in a remarkable world of his own creation in order to insulate himself from a tragedy in his past. He now sees a singular New York and has the charismatic ability to permit others to see the world as he does - full of turrets and castles, terrifying Red Knights and damsels in distress.
Cosplay, a contraction of the words costume play, is a performance art in which participants called cosplayers wear costumes and fashion accessories to represent a specific character.
Cosplayers often interact to create a subculture and a broader use of the term "cosplay" applies to any costumed role-playing in venues apart from the stage. Any entity that lends itself to dramatic interpretation may be taken up as a subject and it is not unusual to see genders switched. Favorite sources include manga and anime, comic books and cartoons, video games, and live-action films and television series.
