"It's basically a fun roller coaster full of nervous laughter and questions that are not usually addressed," he said.
The cast is made up of seven theatre majors, both graduate and undergraduate.
They have all been involved with numerous productions at the university, though few have required them to cross-dress.
According to Marchant, the most difficult part of the play for the actors was this switch of sexes.
In the first act, most of the cast members are playing a different sex than the one they play in the second act.
Marchant said the whole purpose is to make the audience question perceptions of gender roles.
Carpenter said she plays the character Maude in the first act, and then changes to playing Lynn in the second act.
She said she thinks that portraying two different characters is challenging.
"It's kind of strange," Carpenter said. "To do them both in the same day, it's a little jarring. You get 10 minutes to switch gears. I think we all looked for parallels between our characters so we can change instantly."
Marchant said his favorite aspect of the play dealt with its many facets and complexities.
"It's not just a play where you can sit back and relax," he said. "It's very entertaining, but it constantly asks the audience to go with it. There are women dressed as men and men dressed as women. It challenges what we see as normal and what we see as right and wrong. Then it goes a step further to ask why."
Marchant said Cloud Nine is a play that challenges everyone involved -- actors, directors and designers alike -- but also, and perhaps most importantly, it challenges its audience.
Throughout the play questions are raised, attacked and thrown around, only to be abandoned without any definite conclusions drawn.
Carpenter said she liked that the play didn't necessarily get "summed up" at the end.
Marchant hopes that by the end, if it has not surprised its audience, enticed them, aroused them or maddened them, that it has at least moved them.
"What's tricky is how to make the audience feel uncomfortable but make them laugh," Marchant said.
