No one Twice (1985)

Director Jorge Silva Melo has developed a viable, though highly intellectual mystery story about the world of art and culture and murder in this somewhat theatrical presentation. When German artist Bernd Hoffmann (Michael König) arrives in Lisbon to oversee the installation of his paintings in a joint exhibition with another Berlin artist, Hanna Brauer (Charlotte Schwab), Hanna never shows up. Hoffmann is puzzled because he is certain he saw a video sequence with Hanna at the exhibition, and he begins to look for her. Another Lisbon cultural center, a theater, is also having problems that may or may not be related -- and the mystery deepens when Hanna is found dead, either by her own hand, or murdered.
