You get twice the monster mayhem for the same price, and that price is free, at this new monthly screening series. First up is 1967's Monster from a Prehistoric Planet, in which an expedition unwisely takes a scaly baby back to Tokyo--and naturally its parents are upset. Also screened in 16mm is the following Godzilla vs. Megalon (1973), which nicely sums up the plot in its title. If only more movies made that much city-smashing sense. 21 and over. (NR).
