The personalities of runners always seem to run the gamut. On the one hand, regular exercise and fitness is a sign of stability, a display of having chosen the “right” priorities to care for one’s own body. On the other hand, running can become an obsession and a compulsion for a variety of reasons, and can become the vice of somebody with the personality of an addict. The strange relationship between compulsive personalities and physical fitness is at the heart of Benjamin Heisenberg’s Austrian thriller The Robber, an engrossing and complex yet economically straightforward character-driven thriller about a marathon runner who has an addiction to robbing banks. We first meet Johann Rettenberger (Andreus Lust) jogging in a tight square around a small yard, and quickly realize that he’s in prison. As soon as he’s called back inside and is directed to his cell, he continues running on the small treadmill right next to his bed. It’s one of those simple openings that says so much through doing so little, and this characterizes much of The Robber, a film with a deceiving simplicity that makes it all the more compelling.
