Potsdam’s Hans Otto Theater Makes Theatertreffen Debut With Hartmann’s ‘Serotonin’

The 2026 lineup reflects a jury drive for bold forms with topical focus after surveying 739 productions.

Overview

  • Theatertreffen named ten German-language productions for its 63rd edition, which runs May 1–17 in Berlin.
  • Sebastian Hartmann’s Potsdam staging is a five-hour solo adaptation of Michel Houellebecq’s novel performed by Guido Lambrecht.
  • The jury called the production “a masterpiece of theatrical minimalism,” praising Lambrecht’s restrained, precise performance.
  • Hartmann is invited twice this year with Serotonin and Cottbus’s The Captain of Köpenick, a notable double presence outside traditional theater hubs.
  • The selection foregrounds novel-based and actor-centered work, with organizers emphasizing themes from #MeToo to the mechanics of war.
