The Beast in Poltergeist is an amazing practical effect.
A puppet was filmed underwater, creating that eerie, floating glide.
The sound is a lion–tiger mix; MGM loved it so much they replaced their famous logo roar with it.
Poltergeist used it first; it’s still what we hear today
Was at Anime NebrasKon last night. Had a great time and had amazing gifts for amazing voice actors such as @kylehebert , @WendeeLeeVO , and @robbiedaymond. Hope to meet them again and many others in the future.
