CASTLE Hill performers Ben James and Pat Ulloa will play lead roles in the Rockdale Musical Society's production of Next to Normal.
The Broadway rock musical follows Diana as she struggles with mental illness and desperately tries to hold her family and sanity together.
Pat Ulloa plays the pivotal role of Dan, husband to Diana.
Ben James plays Diana's son Gabe.
"The score of this show is spectacular and represents the peak of what contemporary theatre can provide audiences," James said.
"It's cutting edge and leaves what is known about classic music theatre at the door."
Ulloa said at the core of the musical was an "excellent story".
"It is a sad story, however, the intent is for people to walk away not sad but enlightened," Ulloa said.
"I hope it helps open people's minds to the realities of depression."
