About 15 years ago there was a program on PBS I believe, maybe during their beg-a-thon, it seemed to be a documentary about a play(?) because there were clips of the thing and clips of people talking. Anyway, the particular scene in question was of a small child, a boy I believe, on an alien island possibly? Or planet? Not sure, but he awakens from his sleep to see some plants with pods on the top of them and they were sort of sway-dancing in a very creepy manner. There was a choir in the background (sound-wise) and then it jumped to a scene of the young boy frying eggs on a rock, throwing the fry pan to flip them in the air with the plants behind him. I haven't been able to find anything about this (all the searches for alien plants come up with is Little Shop Of Horrors which is definitely not it), and there is no PBS schedule from this time on the net. It scared the bajeesus out of me when I was youngish and I'm dying to find at least something about this.
Sounds like a Day of the Triffids adaptation, maybe? There were several.
