Walk gently, impact strongly

Switch to energy-saving lightbulbs. Reuse your plastic bags. Just say no to suvs. The public is being slammed with environmental messages, so a film needs to spark people's imaginations - not simply finger wag - to stand out in the green movement. That's why sisters Leila Conners Petersen and Nadia Conners went beyond relaying the standard yawn-enducing eco-tips in The 11th Hour, which they co-directed and co-wrote. The feature introduces audiences to lesser-known earth-friendly technologies, like one that can power a nightclub using the movement of feet on the dance floor.
