Justin Kelly’s King Cobra (D+) is a mystery thriller with little mystery or thrills. Set in 2006 as YouTube was coming of age, the film purports to bring a Boogie Nights type allure to the goings-on behind the firewall of an adult film industry in transition. Newcomer Garrett Clayton plays a fresh faced Californian who gets swept up into the porn industry by a closeted amateur producer who makes movies out of his innocuous suburban home, played by Christian Slater. Meanwhile, James Franco and Keegan Allen play rival provocateurs who seem to be acting in a completely different movie universe, like Magenta and Columbia with a death wish. Kelly clearly believes his work is sexier and edgier than it turns out to be. Aside from Slater’s occasionally unhinged performance, there’s very little worth watching here. Fans of Clayton, who is featured in NBC’s Hairspray Live, will get the eye candy they seek but little substance.
