Fox plans to keep hammering away at fracking. He's working on a short documentary on illnesses affecting gas workers and plans eventually to move onto projects on the broader issues of climate and sustainability.
McAleer â¿¿ who in previous documentaries challenged Al Gore's "An Inconvenient Truth" and environmentalists' campaign against Romania mining â¿¿ doesn't plan to make "FrackNation II."
"If you can't say it well in one, you shouldn't need a second one," McAleer said.
