AT THE MOVIES, Woody Allen’s Love and Death (right, with Diane Keaton), a parody of things Russian, is the last of the writer-director’s early-’70s farces; Allen’s seriocomic Annie Hall would win 1977’s Best Picture. His new film, Celebrity, opens Nov. 13. IN MUSIC, ”Fame” nabs David Bowie a Billboard No. 1 single. Bowie won’t achieve that kind of success again until ’83’s ”Let’s Dance.” IN BOOKSTORES, E.L. Doctorow’s Ragtime, mixing famous and fictional characters in turn-of-the-century New York, is a best-seller. In January, a musical version opened on Broadway. AND IN THE NEWS, the Soviet Union and East Germany sign a new treaty that no longer mentions a potentially reunified Germany. The pact is considered to be Communist party leader Leonid Brezhnev’s proof of goodwill between East bloc countries.
