Martin Moszkowicz has joined Philipp Keel to turn Diogenes’ literary catalog into a new pipeline for films and series, linking one of Germany’s best-known producers with the owner of Europe’s largest independent fiction publisher.

The partnership brings together two figures with clear stakes on both sides of the adaptation business. Moszkowicz arrives with a long track record in film production, while Keel controls a publishing house with a rich backlist and has filmmaking experience of his own. Together, they aim to develop screen projects from Diogenes titles, according to reports.

Diogenes does not offer a single breakout title; it offers a deep bench of proven stories that filmmakers have already shown they can turn into major screen work.

That depth matters. Diogenes’ authors include Patricia Highsmith, whose work has fed adaptations such as “Ripley” and “Carol,” along with Patrick Süskind, whose “Perfume” reached the screen, and Bernhard Schlink, another writer with adaptation history. The new alliance suggests a strategy built not on one headline property, but on a broad and durable catalog with international recognition.

Key Facts

  • Martin Moszkowicz and Philipp Keel have teamed up to adapt Diogenes titles for film and series.
  • Diogenes is described as Europe’s largest independent fiction publisher.
  • The publisher’s catalog includes authors such as Patricia Highsmith, Patrick Süskind and Bernhard Schlink.
  • Past screen adaptations tied to Diogenes authors include “Ripley,” “Carol” and “Perfume.”

The timing also reflects a wider hunt for established intellectual property in a crowded global market. Studios and streamers keep searching for stories that arrive with built-in readership, recognizable themes and room for expansion across formats. A publisher like Diogenes offers exactly that: decades of fiction, varied genres and authors whose names carry weight well beyond German-speaking markets.

What comes next will depend on which titles the pair choose to move first and how quickly they can package those projects for buyers. If they pick well, this partnership could do more than generate individual films or series. It could turn Diogenes into a steady source of prestige and commercial adaptations at a moment when the screen business badly wants both.
