Lidia Draper Great example of an old-fashioned, pure-at-heart escapist event movie that doesn't pretend to be anything that it's not and has boat loads of fun being its own ludicrous self.

Allison Davies The film never slows down or bores, plunging from one harrowing sequence to the next.

Brenda The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

Francene Odetta It's simply great fun, a winsome film and an occasionally over-the-top luxury fantasy that never flags.

bkoganbing Tim Holt who besides being a B movie cowboy also was directed at different times of his must have wondered how he came to be in this rather atrocious science fiction film shot on your average household budget for a family on food stamps.His will be the only name you recognize from this cast of never wases in The Yesterday Machine. One of Hitler's top scientists escaped and has set up shop somewhere in the southern USA near the Battle Of Shiloh's site. We know that because a couple of Johnny Reb soldiers show up in the present day of 1963 and kidnap a young coed from that era.Investigative reporter James Britton follows up the story with Holt playing a police detective. Together with coed Linda Jenkins's sister Ann Pellegrino they find the source of the problem. It's Jack Herman playing a mad scientist who if he were a little more mad would be Professor Irwin Corey. Herman was one of Hitler's top physicists and he's cracked the space time continuum and he's even brought back a Nubian slave from the court of Rameses II. We don't get specifics, but Herman is going to a mess with time sufficiently that Hitler will triumph.My high school plays showed better talent than this one did. Poor Tim Holt played it tight lipped and grim which was how he must have felt for being in this wretched film.

oscar-35 *Spoiler/plot- The Yesterday Machine, 1963. A couple of college students stumble on a couple of Civil War soldiers while trying to get car repairs in a lonely rural road. The boy is shot and the girl disappears. The police investigate and find many improbable time travel matters located in an secret professor's lab under a abandoned Victorian house. *Special Stars- James Britton, Ann Pellegrino, Jack Herman, Tim Holt('Treasure of Sierra Madre').*Theme- Time is a river that flows and we are in it.*Trivia/location/goofs- B & W. During Natzi time travel doctor's lecture the chalk drawings change back and forth.*Emotion- A quirky, unique, and stylish low budget science fiction film. I would NOT call this a B-movie or a D-movie due to it's very good script, directing, casting, and acting. The low budget aspects of this film only become apparent with the time machine set piece and German doctor's lab sets. Maybe more money or creativity should have been shown there to treat the film viewer with a better reward for staying around to watch the whole film to it's finale. Exciting, suspenseful and frightening, this film is enjoyable.

MartinHafer Wow. 1963 was an amazing year in the annals of movie history. Not only did it bring us "They Saved Hitler's Brain" but also "The Yesterday Machine", so apparently this year was a banner one for insane neo-Nazi scientists and their kooky schemes. In many ways, both these films are very similar--lousy acting, lousy sets and lousy dialog. The only notable way they are different is that "The Yesterday Machine" lacks a cameo appearance of Hitler's head in a pickle jar! The film begins with a young man being shot (apparently by disgruntled Confederate soldiers who were brought forward in time) and his girlfriend disappearing. This can only mean one thing...a crazed Nazi scientist is running amok experimenting with the fabric of time. So, it's up to a crack team made up of a dull guy and his amazingly untalented and annoying blonde girlfriend to save humanity. While this sounds ridiculous, this neo-Nazi movement only appears to have three members, so the odds aren't that stacked against them! Jack Herman stars as the brilliant but wacky Nazi scientist. Not only can he make time do goofy things, but he can make the drawings on his chalkboard instantly change due to bad editing. And, he also is less subtle than Dr. Strangelove--and a horrible actor to boot. James Britton is the film's "action hero" and based on this performance, I can see why this is his only film credit--he has the charisma of cheese curds. As for the only "name" in the film, once important actor Jack Holt, he's barely in the film at all--just a walk on in the beginning and end of the film. But, since he'd been in "The Magnificent Ambersons" and some other REAL movies, they decided to list him first in the credits. You gotta feel sorry for the guy being stuck in ultra-low budget crap like this and "This Stuff'll Kill Ya" at the end of his once promising career.My favorite bad scene in the film? The one where the Egyptian slave attacks the guard to save the dumb blonde's life. The blonde just stands there as this happens and even does nothing when the stabbed guard then strangles the slave! Talk about ingratitude!! Other great bad scenes are the "magic chalkboard" and the ranting and raving of the scientist--rarely have I ever seen any actor chew that much scenery.Overall, it's a terrible movie in most every way. Understandably, most people who made this film never went on to do much of anything else. The film is bad, but perhaps silly enough to excite a few bad movie buffs.

J. Mike Perkins This film is incredible! It has everything you could hope for in an enjoyable bad film. An amazing plot, Hitler's director of "scientific warfare" Dr. Ernst Van Hauser (played by Jack Herman, an ex-Yiddish theater player who was a drama coach at a local black college) is living underneath a farmhouse in Dallas, Texas (where the movie was made). He is doing time travel experiments and giving lectures to captured subjects about his theories of "Superspectronic Relativity and the Minus Ray" (while his drawings on the blackboard are redrawn twice during his lecture). He states that his theories are far more advanced than Einstein's. He captures a baton twiller and her sister a bad night club singer ("the girl with the orchid voice" the film lets us know) who sings a funny bad song written by the director Russ Marker (I think). The director was an associate of Texas film maker Larry Buchanan and uses some of his stable of actors like Bill Thurman. Also stars a somewhat over the hill Tim Holt as a police detective who immediately knows when a baton twiller disappears in Texas it must by Nazis and Dr. Ernst Van Hauser. Jack Herman's over the top performance as Dr. Ernst Van Hauser is beyond words (William Shatner looks tame and controlled by comparison). Some amazing bad films, with wonderful low budget charm, came out of Texas in the 1960's and this takes its place as a classic along side such bad films as Manos Hands of Fate or any of the Larry Buchanan epics of the period. Highly recommended for bad film scholars. Needs to come out on DVD!
