“No, no! “In” the pants! “In” the pants!”
I remember watching Ants on TV when it premiered in 1977, although I only remember it taking place in a lodge and that all the advertising played up the fact that it ‘starred’ a suddenly famous Suzanne Summers, much like the TV premiere of Logan’s Run blared, “Starring FARRAH FAWCETT!” Despite having no other memories, I would bet the ants were riled up by a building project or something, and that somebody greedy refuses to close something because of Filthy Lucre. Anyway, there’s a pretty good print on YouTube, search Ants TV Movie.
