If you loved Schwarzer Sonntag, try French Connection II
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 John Frankenheimer, and they sit in Action / Thriller territory. If that's the register that drew you to Schwarzer Sonntag, the second film will land in a comparable space — through a different lens.
What French Connection II is
Marseille docks at midnight. A wet coat flapping against a lamppost. Popeye Doyle scans the waterfront. One man’s missing. Another’s staking out every ferry. Soon the chase narrows to the back alleys where the Mediterranean air smells like gasoline and lies.
