The original production used 19 actors comprised of:
- 7 principals (Katherine, Ellie, Fletcher, Mike, Adam, Savannah, Torrey)
- 10 Ensemble (4 adults, 6 teens)
- 2 off-stage swings
In this configuration, the 4 Ensemble Adults doubled, covering a total of 13 diverse featured roles.
The Ensemble cast can be easily expanded by:
- Adding an unlimited number of Adult Ensemble actors, to fill the 13 featured roles and/or to enhance the full cast scenes and musical numbers
- Adding an unlimited number of Teen Ensemble actors to enhance the high school scenes and musical numbers.
