What does a man feel when he suddenly finds himself in a glass cage? What if he has a charming neighbor? It looks like they were both victims of some kind of experiment. Or is she their accomplice? And who are these “they”? Bernard Werber, author of the famous “Ants” trilogy and the novel “Empire of Angels,” offers the reader an original version of the reality show “Behind the Glass.” “Our Human Friends” is successfully shown on the theatrical stage in France. The famous French director Claude Lellouche (“A Man and a Woman”) took this work by Verber as the basis for his new film.
