Watch Movies2Watch. Halcion is the title of the most recent work from Austria´s most productive film studio - that of Dietmar Brehm. The film is hereby named after a sleeping pill which Brehm explained in a letter "induces pastel colored dreams and watery images". Its appearance leaves little doubt that a key to the film lies in its title: we are given to see the vision of a dream that has coagulated to film.
