The trailer for ‘Strange Magic’ boasts that the film comes “from the mind of George Lucas.” That great big brain has dreamed up some of the greatest movies of all time. But it’s also produced its fair share of clunkers as well. (Apologies, ‘Radioland Murders’ devotees.) It’s unfair to write off a movie based on a 150-second trailer, but so far, ‘Strange Magic’ looks a lot closer to the latter than the former. Whoa, this looks insane.
