4D Man

4D Man (UK title: The Evil Force; reissued in the US as Master of Terror) is a 1959 American science fiction independent film,produced by Jack H. Harris from his own original screenplay and directed by Irvin S. Yeaworth Jr.

Plot

Brilliant but irresponsible scientist Tony Nelson (James Congdon) develops an electronic amplifier that he hopes will allow any object to achieve a 4th dimensional (4D) state. While in this state that object can pass freely through any other object. However, Tony failed to pay attention to the overload, which sparks an electrical fire that burns down his lab, resulting in the university terminating his contract. Now unemployed, Tony seeks out his brother Scott (Robert Lansing), a researcher working on a material called cargonite that is so dense as to be impenetrable, to help him with his experiment.

Scott is underpaid and unappreciated at his job but does not have the drive to challenge his employer, Mr. Carson, for greater recognition, especially since Scott has been the driving force behind the development of cargonite (named after Carson, showing he is grabbing much of the credit for Scott's work). When his girlfriend (Lee Meriwether) falls for Tony, an enraged Scott steals Tony's experiment and starts playing with it, eventually sending himself into a 4D state. When demonstrating this to Tony, Scott does not turn on the amplifier power yet successfully passes his hand through a block of steel, meaning Scott can now enter the 4D state via his own will. Tony is amazed but warns Scott not to reveal this until he can further test it for any side effects.
