The Mark Wahlberg vehicle Broken City, which opens Friday, is a solid, old-fashioned detective movie. Barring a speech about social equality for gay couples and some superfluous helicopter shots, the film feels a lot like a mid-40s noir programmer. Wahlberg’s flawed private investigator (a former police detective trying to earn his keep), the casual intimations of political corruption, director Allen Hughes’s gritty-but-affectionate portraits of marginalized neighborhood communities: all these qualities agreeably recall a second-tier Robert Siodmak effort like Cry of the City (1948) or The File on Thelma Jordan (1950). And like a good old noir programmer, the movie really comes to life when the character actors in the supporting cast get to strut their stuff. The most memorable bits belong to Barry Pepper as a JFK-worshipping mayoral candidate, Jeffrey Wright as a hard-ass police commissioner (his soft bald cranium hinting at a fascinating secret life), and, in far too brief an appearance, James Ransone as a wealthy developer’s bratty son.
