What if intelligence could be increased with surgery? Are smarter people happier? Charlie Gordon isn't going to be any happier about having his IQ raised from 70 to 180. But the result is not permanent. The sensational change takes place in a few months, followed by degradation. From his diary - thanks to the psychologist writer's great empathy - we can learn how the mentally retarded person sees his own situation, how complicated the relationship between the experimenter and the experimental subject is, how intellectual and emotional development can be separated from each other. It is thought-provoking how the change in Charlie's intelligence affects the feelings of those around him, who have turned from a retard into a genius. Ernő Fekete's great performance presents the fantastic story of Charlie Gordon and Algernon, the experimental white mouse, with dramatic power.
