“Copshop” (*1/2 out of four) was a ludicrous thriller about a slimy con artist (Frank Grillo) who purposely gets himself arrested to hide out from a lethal assassin (Gerard Butler) but plans go awry when that assassin gets himself arrested also and winds up in the same jail cell and (!) another even more nutty assassin (Toby Huss) shows up to kill all of them while the arresting rookie cop (Alexis Louder) tries to make sense of all this and stay alive. Yet another over-the-top and stupid thriller from writer/director Joe Carnahan (“Smokin’ Aces”, “Narc”) with his usual nonstop violence and ugliness; this one gets sillier with each new plot twist. Louder’s strong performance is one of film’s few virtues. Another imitation of “Assault On Precinct 13” that’s an assault on one’s intelligence instead.
