If you loved El monstruo está vivo, try La Sustancia Maldita
Un puente entre una película que ya has visto y una que casi nadie ha cruzado. Esto es lo que comparten, y lo que la segunda hace que la primera no hace.
Lo que comparten
Both films are directed by Larry Cohen, and they both carry the 3am cult mood tag, and they sit in Horror / Science Fiction territory. If that's the register that drew you to El monstruo está vivo, the second film will land in a comparable space — through a different lens.
3am cult
What La Sustancia Maldita is
Abandoned mine; midnight; a pickaxe. A white, living goo bubbling up from the earth becomes the next national dessert craze. A corporate spy, a kid, and a militia leader seek the source. Cohen's consumer-horror is best enjoyed as a midnight snack.
