Here we go again. The Los Angeles Times is reporting that the California Science Center, an organization affiliated with the Smithsonian, is facing a lawsuit from a group called the American Freedom Alliance. The group planned to rent the Center's IMAX theater in order to show a movie called "Darwin's Dilemma," which attacks the theory of evolution and promotes intelligent design. When the anti-evolution, pro-ID Discovery Institute stepped in, the Center used a clause in the contract to cancel the showing, attracting suits from both groups.
