The real Brockovich is back on the big screen in the new documentary "Last Call at the Oasis," which opened in New York and Los Angeles on Friday and will spread to other cities throughout the month. The 51-year-old activist is among various environmental experts cited in the 100-minute film, which explores challenges related to the planet's dwindling and increasingly polluted water supply. The film shows her visiting a community in Midland, Texas, where water comes out of the tap bright green. [...] a film comes out or there's some convergence and people realize: "Oh (expletive), this is in my backyard." All this contamination still sits in the ground, that could have been cleaned up 20 years ago, that could have prevented an aquifer from being destroyed, that could have prevented another community from coming down with disease, and we've done nothing.
