4D Man is a very entertaining Sci Fi thriller that utilizes the talents of actor Robert Lansing to their fullest extent. He strikes the right cord as Dr Scott Nelson. Using the research gathered by his brother Dr Tony Nelson, and the data he has gathered through his own work Nelson discovers a method of projecting himself into a fourth dimensional state which allows him to pass through solid objects. The downside is that each projection he attempts causes his body to age very rapidly. He then discovers that with his touch he can absorb the life energy of other living creatures which will renew his own life force and restore his youth. This has the added effect of killing those whose energy he has drained.
The old adage that "absolute power corrupts absolutely" comes through as Nelson allows his pent up frustrations to surface and he uses his powers to rob, and take revenge on those who feels have wronged him.He eventually is able to project himself through shear force of will. When he finds that his fiancé and his brother have fallen in love with each other and have gone to the authorities about him, he targets them both for death.
4D Man has an interesting and unusual premise for a science fiction film. Irvin S Yeaworth Jr directed and did a first rate job of making an absorbing and tightly wound story. Lansing was a low key actor who generally underplayed his scenes. While it didn't not always work, it's the right method for Dr Scott Nelson in this story.Good special effects also help. Sci Fi fans and fantasy buffs will enjoy and appreciate 4D Man.
