Reeve Carney can really thank Julie Taymor now. He’s been plucked from his grueling job playing Peter Parker in “Spider Man: Turn off the Dark” to star in the official bio film about late singer Jeff Buckley. Before “Spider Man,” Carney had his own pop group but no acting credits. Now he’s an actor and acrobat as well, thanks to Taymor. The Buckley movie is called “Dream Brother” and it’s based on David Browne’s excellent book about Buckley. Jake Scott will direct. This is the only Jeff Buckley movie with the singer’s music. The rights belong to Buckley’s mother. Another movie starring Penn Badgley is being made in which the “Gossip Girl” star will play Jeff, but it takes place during a tribute concert for Buckley’s late dad, Tim. The only song to overlap in both movies could be Leonard Cohen’s “Hallelujah.” Otherwise, “Dream Brother” will have all the Jeff Buckley music and the authorized story of his untimely death. Carney will need time off to make “Dream Brother”–he deserves it after the “Spider Man” experience. His alternate, Matthew James Thomas, is ready and able.
