Science teaches us that arachnids are staunch monarchists, while ants are proponents of territorial expansion. Neither of these geopolitical bents works out all that well for us humans, as is demonstrated in both of the features in tonight’s Drive-In Mob. First up, at 8pm EST, is Kingdom of the Spiders, followed, at around 9:30pm EST, by Empire of the Ants. Both films are available for streaming from lord internet, in the case of Kingdom of the Spiders, from YouTube, and in the case of Empire of the Ants, from Netflix Instant. All you need to do to either follow or tweet along is use the #DriveInMob hashtag on Twitter… and of course check out the official Drive In Mob site for more explicit details.
