This genre-bending documentary will follow fifth-generation Montanan performance artist Marla Goodman and her theremin-playing alter egos, Polly and Dolly Vinyl — fictional fraternal twin sisters with backstories drawn from Marla’s own life.

Part artist portrait, part fictional narrative, and part celebration of unexpected art in unexpected places, Polly and Dolly (and Marla) (working title) will depict the humor, self-doubt, and self-discovery of an artist at work.

The production, which began in spring, will follow Polly and Dolly to Butte, Helena, Boulder, White Sulphur Springs, Livingston, and surprise stops in between. The film will be completed by early 2027.
