This columnist will be Straw Dog-ging it down in Shreveport, Louisiana, at the end of next week. Roughly two days, in and out. Director-writer Rod Lurie, costars James Marsden, Kate Bosworth, Alexander Skarsgard, James Woods and Dominic Purcell. I’m going to definitely visit the Stray Cat on Travis Street — i.e., the place where Josh Brolin and Jeffrey Wright got into a situation with the local fuzz during the shooting of W.. The wifi had better be good or else.
