The DVD Bonus Footage contains several short films: "An Alternate Approach", "More from Do You Care Truck", "Extended Shishamareff", "Rick and the Bar Mitzvah", "We Could Just Adapt", "A Message from the North" (with Jake Gyllenhaal making a visit), "Jeff Nachmanoff and DAT" (with more commentary about the importance of the 2004 Roland Emmerich film "The Day After Tomorrow" (20th Century Fox), where entertainment engages the public more than documentary "information".
There are also five "Activist Extras": "Everything's Cool at Sundance's Leveraging Film Festival". "Set Up: A Day of Action", "Biofuels High", "Green Jobs Revolution", "Youth Unite for Clean Energy". The last short, the most substantial, presents youth undergoing a 3-day fast in front of the White House (not just a 30 hour fast) because the US wouldn't sign the Kyoto agreements. Another student drops out of college (sacrifices) to start a green "social movement". The relevant web link is Climate Challenge here.
These short films come from "Working Films".
