Its walls are decorated with 1930s murals, painted by local painter and sign writer George Biles.
As well as performances and cinema, the theatre hosts weddings and other events.
Ryan Holmes, head of commercial at agent Symonds and Sampson, said: “Whilst other cinemas have floundered, the Electric Palace has survived and flourished, largely thanks to loving restoration and modernisation of the building by its current owner.
“Improvements include the largest cinema screen in Dorset, a state of the art digital projector and sound system, and upgraded bars, hospitality, and backstage areas.”
