Universal Theory is Timm Kröger's first official feature film. Selected in 2014 at the Venice Film Festival for Critics' Week, it has never been distributed theatrically, neither in Germany, its country of origin, nor elsewhere.

Black and white work is as much a Hollywood melodrama as a film noir, a metaphysical thriller as a homage to the seventh art. "In what world are we living?" is the whole question in the preamble to this film, the one that has obsessed Johannes Leinert.
