An "angry and disappointed" Christopher Reeve is accusing the Catholic church and President Bush of obstructing research which might help him walk again. The paralyzed Superman star tells Britain's Guardian newspaper that Bush caved in on the issue of embryonic stem cell research after the Catholic church expressed opposition to cloning. "If we'd had full government support, full government funding for aggressive research using embryonic stem cells from the moment they were first isolated," he says, "I don't think it unreasonable to speculate that we might be in human trials by now."
