Writer-director Cameron Crowe’s autobiographical fourth feature (2000)after Say Anything . . . , Singles, and Jerry Maguireconcerns the adventures of a 15-year-old rock journalist (Patrick Fugit) touring with a band (the fictional Stillwater) in 1973 for Rolling Stone. This has much of the warmth and feeling for adolescence that Crowe displayed in his first feature, though the slick showboating of Jerry Maguire isn’t entirely absent either. Part of what Crowe’s exploring here is the ethical confusion that can arise from the differences between being a journalist and being a groupie. With Billy Crudup, Frances McDormand, Kate Hudson, Philip Seymour Hoffman (especially good as the legendary rock critic Lester Bangs), Zooey Deschanel, and Anna Paquin. 122 min. (JR)
