Video almost killed the radio star. Kurt Andersen barely survives a visit to a talk show that takes place entirely within the ultra-violent digital game world of Halo 2. And it’s an American Icons double header: we offer an appreciation of Charlie Chaplin’s character the Tramp, who may be the most endearing icon in the history of cinema, and then we journey back in time in search of the original steel driving man, John Henry. Plus, Kurt pays tribute to the innovative moviemaker Robert Altman, who died this week.
