Dr. Laurence, a once-respectable scientist, begins to research the origin of the mind and the soul. The science community rejects him, and he risks losing everything for which he has worked. He begins to use his discoveries to save his research and further his own causes, thereby becoming... a Mad Scientist, almost unstoppable...
Unfortunately the movie The Man Who Changed His Mind is not yet available on HBO Max.
