Watershed School will shed the famous water of Mary Zimmerman’s “Metamorphoses” but — thanks to a combination of imaginative stage techniques and the centuries-proven power of Ovid’s storytelling — promises a theatrical immersion.

The play will be presented Friday and Saturday, April 10 and 11, at 7 p.m. at the independent high school, located in the Knox Mill complex. The entrance, directly on the corner of Washington and Mechanic streets, leads right into the small space known as the Common Room. As might be expected at a school with eight or fewer students per year-class, it should make for an intimate experience.

“If you get lost coming back from the bathroom, you’ll be in the play,” said one of the cast members the week before production.

The 10-student cast and two-student crew have been working on the production since January in the theater class taught by English teacher Brian Boyd. Last year’s “Much Ado About Nothing” was a full-school production, presented at the Camden Opera House; usually, the annual play is confined to sophomores, juniors and seniors. While his “Metamorphoses” cast joked it is because they are “so much more mature,” Boyd said the policy has to do with the demands of Watershed’s freshman year.

“Metamorphoses,” which was nominated for the 2002 Best Play Tony Award (and won for Best Direction), offers a contemporary, sometimes anachronistic, take on the Roman poet Ovid's mythological tales — specifically those that involve water. Zimmerman stages her play around — and in — a pool of water. It makes for magic from the audience’s perspective … and a huge technical challenge on the production side. Given the space and budget constraints, the pool was never really considered at Watershed.

“But that doesn’t mean we weren’t thinking about water,” said student Leslie Ryan, who lives in Belfast.

As they began working on the show, the theater class considered all kinds of water stand-ins, including glass beads and fish tank gravel. In the end, blue yoga mats will suggest the rivers, sea and springs that figure into the stories.

A large white screen, made of butcher paper, hanging in front of the locker wall will help the production exploit one of the oldest tricks in the theatrical trunk — shadow projection. Techie August Rudy has made a trireme out of cardboard, wood and string, reinforced with a yardstick, while cardboard branches — and the occasional student — will create other shadowy illusions. All will help set the scene for stories of Zeus, King Midas, Narcissus, Eurydice and more, as will the judicious appearance of “lightning” via the transom windows.

Classic props such as oars, ladders, lamps and a trident have been gathered or created; the production also uses cell phones and other 21st-century items. Costumes include changeable headscarves for the female cast members and other things that can be quickly switched, since each of the performers plays multiple roles — gods and goddesses, kings and beggars, sailors and singers.

Thanks to in-cast talent, music is woven throughout the Watershed production, including recorded passages to introduce scenes and live performances on saxophone, flute, fiddle and more. Latin, a subject offered at Watershed, also makes an appearance; Boyd praised the playwright for “preserving the playful, dreamlike, trickster quality of Ovid’s Latin poetry.”

The fast-transitioning tales will be presented two nights only and admission is free, although donations are welcome. For more information, call 230-7341. For more information about the nonprofit Watershed, founded in 2003, visit watershed-school.org.
