• Doubling: When an actor plays more than one character in a production. Most times this is done for economical reasons but it can be that because an actor would like to take on more than one role in the performance.
• Receiving house: (sometimes called a roadhouse) a theatre which does not produce its own repertoire but instead receives touring theatre companies, usually for a brief period such as three nights or an entire week. The incoming company may receive a share of the box office takings or a minimum guaranteed payment. West End theatres in London and most Broadway theatres in New York are also receiving houses, as the venue solely provides facilities to the incoming show even though the production may stay for many years. Theatres which produce their own shows are known as producing houses, and some regional theatres will do both.
• Understudy: A person who learns the part of a specific character or characters. Should the performer who is cast in those roles be unable to perform their part due for any reason (e.g. illness, injury etc.), the understudy will step in and perform the role. Also known as an Alternate.
