Joan Renier. The Jenus Film Festival, currently showing at the Orson Welles, comes to Cambridge at some theater or other every year, and it's so respectable you can hardly stand it--Sergman, Truffout, and on and on. It gets boring after a while--you want to go take in a good Charles Bronson Hick. But there's one thing on the Janus bill that's worth a thousand copies of Film Quarterly: the Renoir double bill of The Rules of the Game and Grand Illusion. When people talk Citizen Kane, and Potemkin, Birth of a Nation and The Seven Samural, if they don't talk about these two they're crazy, because they could give any motion picture ever made a real run for the ultimate superlatives.
