If you loved Family Business, try Das Mörderspiel
Eine Brücke zwischen einem Film, den du schon gesehen hast, und einem, den kaum jemand kennt. Das teilen sie, und was der zweite macht, was der erste nicht macht.
Was sie teilen
Both films are directed by Sidney Lumet, and they both carry the pitch black mood tag, and they sit in Comedy / Crime territory. If that's the register that drew you to Family Business, the second film will land in a comparable space — through a different lens.
pitch black
What Das Mörderspiel is
Dark Manhattan theater winter rain drumming on pavement a lone typewriter. A desperate playwright and his student clash over a script. Sidney Lumet directs with dark humor.
