From what I remember from this movie, it looks old, possibly from the 1980’s, 90’s, or 2000’s, I’m not sure. It’s an American Sci-fi movie in English I partially saw on TV in color twice when I was a teenager. I don’t know anything about the actors/actresses’ names.
In the movie, I only remember a few scenes. A scientist has a rival scientist whom he forces to cancel some sort of rocket launch. At one point, the rival scientist was seen with his strong driver holding the scientist and his friend at gunpoint unaware that it was all being recorded on a security camera. Then, when the rival scientist is at a conference and after the good scientist and his friend escape with the help of his ghostly-like “girlfriend” and the strong driver has been dealt with by the good scientist, some reporters show the footage involving the gunpoint to everyone and they mention and claim at one point that he actually “discovered New Jersey.” instead of some new planet or something.
At the end, after the rival scientist has been arrested when trying to flee to no avail, the good scientist returns home, closes his eyes, and uses a special somewhat magic, space stone he has in one hand in order to turn his beautiful, somewhat ghostly-like woman girlfriend whom he has been in love with since probably the beginning into a real woman at the end of the movie.
At one point in the movie, I remember the good scientist was playing chess with the ghostly-like woman too.
P.S.: The woman was seen wearing a white dress and she was a blonde throughout the movie. The rival scientist’s name was called Dr. Mein or Mine-bender or heimer or something. I’m not so sure.
Note: It is not “The Man with two Brains”, “The Adventures of Buckaroo Banzai Across the 8th Dimension”, or “Flubber” either.
