"The Rocky Horror Show" pokes fun at the low-budget science fiction movies of the 1950s and the repressed society these films were made for. The NonProphet Theater Company has to contend with a low budget in their current staging of the 1973 musical by Richard O'Brien, but the group uses its resources well in an entertaining production. It's a naughty treat for the Halloween season.

"Rocky Horror" follows the journey of Brad Majors and Janet Weiss, a clean-cut young couple who look forward to settling down in the conventional marriage their society expects. A flat tire during a storm forces them to seek refuge in the castle of Dr. Frank 'N' Furter, a mad scientist who wears women's clothes instead of a lab coat. He is about to give life to his own version of the bride of Frankenstein when the unexpected visitors arrive.

Frank 'N' Furter's freaky servants quickly get Brad and Janet out of their wet clothes, and the rest of their inhibitions soon follow.

Robert A. Mitchell's makeup gives Frank 'N' Furter a Japanese look. It's an interesting choice for a character who cannot be too unusual. Mitchell has a rich singing voice and throws himself into his songs with abandon.

Erin Almand and Cliff Turner do a fine job of showing how the enticements of the castle lure Janet and Brad away from their unquestioning conformity at the start of the play. Their musical numbers contain nice characterizing touches as well as lively singing.

Leo Gregory Stoff has the physique required to play Rocky and gives an appealing innocence to Frank 'N' Furter's muscle-bound creation. Stoff is reprising the role he played in another production earlier this year. So is his sister, Paula Stoff Dean. Her Magenta is appropriately creepy, as are James Cougar Canfield's Riff-Raff and Laura Coppinger's Columbia. Robert Ashton brings the right air of detachment to the narration.

The energy is infectious in the musical staging by Mitchell and director Sarah Lynne Holt and the choreography by Kay Allen. The actors make repeated forays into the audience and occasionally end up in someone's lap.

The excellent band includes John Thomas (keyboards), Nick Baur (guitar), Michael Monsey (bass), Matt McKeever (saxophone), and Robin Weatherall (directing from the drums). Their playing is always spirited but never overpowering. The amplification could still use some fine tuning, but the lyrics are almost always understandable.
