Understudy

In theater, an understudy, referred to in opera as cover or covering, is a performer who learns the lines and blocking or choreography of a regular actor, actress, or other performer in a play. Should the regular actor or actress be unable to appear on stage, the understudy takes over the part. Usually when the understudy takes over, the theater manager announces the cast change prior to the start of the performance. Coined in 1874, the term understudy has more recently generally been applied only to performers who can back up a role, but still regularly perform in another role. Performers who are only committed to covering a part and do not regularly appear in the show are often referred to as standbys and alternates. Standbys are normally required to sign in and remain at the theater the same as other cast members, although sometimes they may call in, until they are released by the production stage manager. If there is no doubt about the health of the actor being covered, or there are no hazardous stunts to perform, a standby may be released at the first intermission, if not before. At times, standbys are required to stay within a certain area around the theater (10 blocks in New York City is a common standard). Today, the standbys must also have a cell phone so that at any time they can be called to the theater. Alternates, like standbys, do not have a regular character in the production, but they are scheduled to go on for a physically and vocally challenging role for a certain number of performances a week. Examples of this are the title role in Evita, Christine in The Phantom of the Opera, Peter Parker/Spider-Man in Spider-Man: Turn Off the Dark, and Evan Hansen in Dear Evan Hansen. In musical theater, the term swing is often used for a member of the company who understudies several chorus and/or dancing roles. If an understudy fills in for a lead role, a swing acts the parts normally performed by the understudy. A super swing or universal swing is a swing who commutes around the country as needed to act in various productions of a widespread show.
