Robert Lansing is a scientist who can walk through walls (and everything else) in this very good and quite different Sci-Fi B-movie. The first thing to note is that this is in color. It brings a more modern feel that separates it from the majority of other black and white Sci-Fi films of its day. Another surprising difference is the use of the brash jazz score. The music seems hopelessly out of place until later in the movie when Lansing's character is on the run from the law. The music then gives it a classic gritty crime drama atmosphere. The special effects which involve Lansing reaching through solid objects and walking through doors and walls is convincing enough. The transformation of Lansing from a brilliant mild-mannered scientist to deranged killer is very harsh. His fall from grace is fast and hard as he almost immediately turns to the darker benefits of his newly acquired power. Fellow scientists played by Lee Meriwether and James Congdon also sell the remarkable story because they realize that they can't "cure" Lansing's character and join the fight to destroy him. The open ending is perfect and its any viewer's guess as to what became of the scientist.
