Sept. 8-14: Bill Nye brings the science, Saved by the Bell has a new class, Ricki Lake and Ellen and Conan start talking, a brand-new Superman, Paul Giamatti is a comic-book legend, Kathleen Turner is undercover, HBO goes to the circus, Robert De Niro’s family gets meta, Eli Roth has the fever, British gangsters get peaky, and the Warner Bros. and the Warner sister Dot. All that and more as we look 30, 20, and 10 years ago!
