After Crowley (and its 1990 sequel, Cenizas de Crowley/Crowley's Ashes), Islas went on to bigger and better things.
His next films included an adaptation of a gruesome horror story by "the Poe of Uruguay", Horacio Quiroga (El Almohadón de Plumas/The Feather Pillow, 1988); a science fiction film (Rumbo a la Oscuridad/Journey Into Darkness, 1992); a moody Gothic (La Trampa/The Trap, 1992) and a werewolf movie (Plenilunio/Full Moon, 1993).
In the mid-1990's, he moved to the United States. From his new base in Chicago, Islas has taken on such familiar subjects as ghosts, zombies and lesbian vampires, putting his personal stamp on all of them. He's even dared to step in where so many have failed in recent years: to make his own, unique version of the Frankenstein story.
