If you loved Roger Corman's Frankenstein, try Gesandter des Grauens
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 Roger Corman, and they sit in Horror / Science Fiction territory. If that's the register that drew you to Roger Corman's Frankenstein, the second film will land in a comparable space — through a different lens.
What Gesandter des Grauens is
Los Angeles. Perpetual day. A black sedan. An emotionless humanoid arrives from deep space, his mission simple: harvest human blood. Failure is not an option, though Earth customs prove unexpectedly strange. Corman's cheapie offers surprisingly chill paranoia.
