Note: If you seek holiday-themed reading, I’ll be posting tomorrow about Christmas traditions in medieval England at http://www.seducedbyhistory.blogspot.com/.
Double casting: two actors play one role.
The first time I was double cast was in eighth grade…as Oliver in my junior high’s musical, Oliver! Being very short with short hair, I was chosen to portray a boy. The other Oliver was an actual boy (whose older brother was single cast as the Artful Dodger). I’m not sure if the school was trying to give more students the opportunity to participate or thought the role was too large for one student to perform at every performance. But after all the rehearsals, after learning all of the lines, songs, choreography and blocking, I would have liked do to more performances.

Happy Holidays!
