First, in "Yongary, Monster from the Deep," an atomic blast in South Korea releases a gasoline-guzzling reptilian creature from the depths of the Earth. When the fire-eating beastie goes on a rampage in Seoul, can he be stopped? Yeong-il Oh, Jeong-in Nam star. Then, the Saturday matinee favorite "Konga" stars Michael Gough as a British scientist who uses a serum to transform a lab chimp into a gorilla. By hypnotizing the animal, he gets it to kill his enemies before it grows to king-size (or is that "Kong-size"?) proportions and proceeds to smash up London. With Margo Johns, Jess Conrad. 170 min. total. Widescreen; Soundtracks: English Dolby Digital mono, Spanish Dolby Digital mono; Subtitles: English, Spanish.
