The Mike Russell Power Hour steams like an overcaffeinated freight train through the fallout of Comic-Con, day 1: A festival of marketing and advertising fed to cheeping fanboys seated in a sturdy nest of pop-culture. Topics include: Who cast Jonny-Cab as Jeff Bridges in the new Tron trailer, why Helen Mirren with a .50 cal sniper rifle might be the sexiest thing onscreen this year, Sam Neill interrupts Mike Russell's perfunctory review of the Adult-Contemporary Smooth Groove action film "Salt," How Johnny Knoxville managed to show up 3/4ths of all the executives in Hollywood with Jackass 3D, Scott Pilgrim, World War Z, and Disney's "Cthulhu," coming soon to screens near you.
