#6 Dangerous Liaisons by Pierre Choderlos de Laclos
Pitch: High society sexual debauchery and scheming in lavish 18th century France.
Upside: Les Liaisons Dangereuses has been successfully adapted into a play and a film. Why not a TV series? It’s Downton Abbey meets 50 Shades of Grey! Bonus: The rights are seemingly in the public domain.
Downside: Tough to think of a downside as long as the network can show R-rated content. The story needs expanding beyond the novel’s tale, but TV writers do that sort of thing every day.
Perfect Home: Showtime
