“Red Carpet” (* out of four) was an unbearable melodrama about an aspiring actress (Wittie Hughes) who arrives in L.A. but soon gets sucked into the underworld of drugs and sex trafficking and has to use all her acting skills to physically and psychologically survive. Highly exploitative and ugly film wallows in the lurid morbidity it seems to be decrying. Hughes is good under the circumstances but can’t do much to enrich this deeply unpleasant film. Writer/director Scott Altman is a relative of director Robert Altman but let’s just be kind and say this is no “Nashville.”
