@p Ironically Oppenheimer was 90% practical effects, just like the eighties used to make.

Terminators were also Stan Winston, Total Recall was Rob Bottin for the creatures / makeup effects and ILM for matte shots, Alien was H.R. Giger himself working on the creatures with a technical crew and Brian Johnson of Space: 1999 fame for the models, and most of Romero's later films were Tom Savini who you may recall as Sex Machine in From Dusk Til Dawn.
