You should expect to learn nothing about the life of "Weird Al" Yankovic from the new film Weird: The Al Yankovic Story. That's because in keeping with his history of parody and comedy and sendups, the film, starring Daniel Radcliffe, is itself a sendup of biopics. From unsupportive parents who hate the accordion to a scandalous affair with Madonna, the movie is an avalanche of fictions mixed with the occasional dash of truth.
