Greenpeace advert made for Greenpeace Germanys 25th anniversary for cinema audiences to raise public awareness on the ecological issues affecting the planet. New end graphics refering the jubilee. Eddie Izzard plays Brik, a laconic, cynical alien who thinks earth's not worth the cost of invasion. Set against him is the idealist Zarg, played by Joe McFadden, who believes humans should be given the chance to prove themselves. Their leader Robin, an apathetic pen-pusher, is played by Jim Broadbent. The three argue over the relative merits and failures of earth and try to decide whether it's worth their attention.
