Herein, director Joel Schumacher does what he does best. He chases a lowest-common-denominator audience by invoking a Hollywood tradition: smart-ass black comic must team up with authority-figure white cop to solve some crime or another, with the extreme-Odd Couple pairing promising (but rarely delivering) low-brow fireworks and culture-shock cuteness. Chris Rock discovers his late twin brother was a CIA agent and is conscripted into posing as the absent sibling and partnering with a patrician Sir Anthony Hopkins. Rock is a fine, risky comedian on stage and recordings, and Hopkins has proven his acting chops for decades in better movie fare than this. But here, the material diminishes both their talents. Rock ends up looking befuddled and Hopkins seems supremely bored. What's next... Bernie Mac meets Judi Dench?
