It always starts this way: A specialized network builds a constituency with influential programming, then gradually alters its format to accommodate a wider audience. But I don't know if anyone saw that coming with The Weather Channel, which announced today it will augment some of the cable's most influential programming on cable with weekly, weather-themed Hollywood movies. First up on Oct. 30: The Perfect Storm, followed by March of the Penguins, Deep Blue Sea, and Misery -- yes, that Misery, which begins in a blizzard. Great. Surely Menage a Tornado, Born in a Tsunami and other stimulating Weather Channel original programming isn't be far behind. [AP]
