The Yesterday Machine is a regional American science fiction film written, produced, and directed by Russ Marker. Various sources give the film's release date as 1963, 1965, and 1966. It stars Tim Holt, James Britton, Ann Pellegrino, and Jack Herman. In the story, a newspaper reporter, a nightclub singer, and the singer's sister fall into the hands of a mad Nazi physicist who has developed a time travel machine with which he intends to snatch Adolf Hitler from the past, teleport him into the present, and forever bring the world under the brutal domination of the Third Reich. Plot College drum majorette Margie De Mar (Linda Jenkins) twirls her baton as boyfriend Howie Ellison (Jay Ramsey), a cheerleader, tries unsuccessfully to repair his broken-down car so that they can get to a football game on time. As they walk to a farmhouse for help, they stumble upon two American Civil War Confederate soldiers. Confused and frightened, they run away, but Howie is shot. He stumbles back to the car, collapses, and is taken to hospital by a passing motorist. Margie simply disappears. Newspaper reporter Jim Crandell (Britton) is covering the shooting. At the hospital, Dr. Wilson D. Blake (Charles Young) tells him that Howie had been struck by a minié ball fired from a Civil War-era rifled musket. Police Lt. Partane (Holt) and Det. Lasky (Robert Kelly), who are investigating, go to the nightclub where Margie's sister Sandy (Pellegrino) is singing. Partane informs her that Margie has gone missing. Sandy asks Jim to take her to the site where Margie vanished. They find nothing. Next morning, Jim discusses the case with Partane. He tells Jim that at the end of World War II his army unit had liberated an unusual concentration camp, in which the prisoners were all young and well-fed. A nearby bombed-out building contained an electronic machine that couldn't be identified. Partane speculates that the machine had been a time travel device. The commandant of the camp, physicist Ernst Von Hauser (Herman), was never captured. Sandy and Jim return to where Margie disappeared. Still not finding anything, they walk through an unexpected, unexplained, invisible something in a field and find themselves in 1789. Then, suddenly, they're beneath the farmhouse, in Von Hauser's lab, teleported there by a time machine which operates on the principle of "super spectronic relativity," a discovery of Von Hauser's in which light is made
