From East Berlin to Hollywood: Literary Resistance in Jurek Becker's 'Jakob der Lugner'
By allowing multiple versions of events to co-exist within his story (including two different endings), Becker's narrator creates an ambiguity that encompasses both fact and fiction and resists the notion of a singular Holocaust narrative. Unfortunately, the East German version of Jakob der Lugner, which is generally considered the superior cinematic adaptation, essentially deletes the narrative frame that carries the bulk of this resistive move.
