This was originally named "The Gateway." They have relaunched this crap-film under the name "Alpha Gateway." What a crock.
People who are not avid Sci-Fi enthusiasts may rate this film higher than I did. The plot-holes in this film are beyond massive. The scientists are anything but as the so-called "trials" consisted of an apple, a camera, then a human being. Moreover, the "frequency" issue was a joke.
They sent an apple through the sending pod that did not materialize in their receiving pod. When the apple did not materialize in their receiving pod they suddenly concluded, in a very non-scientific way, it went to a parallel universe (what a leap). Then they concluded the apple did not come back because the beings in the parallel universe must be on a different frequency. Question, if their equipment is on a different frequency, how did they receive the apple? EXAMPLE: If I broadcast a radio signal and your receiver is tuned to a different frequency (as claimed in this film), how will you hear me? How can I send you instructions to change frequencies in order to hear me, if you can't hear me in the first place? The phony solution used in this movie was to write the correct frequency on a paper and send it through. Again, if the other "beings'" equipment is on a different frequency, how did they receive the note OR the apple? Sending the note to change the frequency apparently solved the problem as the apple was then sent back.
Next they sent a video camera through. The parallel universe scientist was on the recording that came back. After seeing the camera and apple come through, the scientist decides to send herself through. I imagine her thoughts were "Hey. The apple and the camera worked. So why not a human? We don't need no stinking guinea pigs." Then, without hesitation nor reservation, she brings the alternate husband back to this universe because hers recently died. The duplicate husband turns out to be a homicidal maniac. Of course no one must know this is a duplicate husband.
The assistant builds another teleporter in his basement, which are basically a bunch of wires dangling inside a cardboard box. Somehow his house circuit breakers and power lines are designed to provide 300 "Petawatts" of power without blowing a fuse.
There is so much more wrong with this film it is too much to write. It is possible they may have been trying to make a Dr. Who-esque film. If so their failure is epic. If not, they simply made a horrible film.
