Some brief disappointing news as HBO is passing on Alan Ball’s latest genre drama project, “All Signs of Death.” The Ball-directed pilot was based on Charlie Huston’s noir novel, “The Mystic Arts of Erasing All Signs of Death,” about a slacker who joins a crime scene clean-up crew. HBO has decided to not opt for a series greenlight, which should also keep Ball focued on his hit “True Blood.” It’s a bummer to see a genre project go kaput, especially on the heels of something as successful as “True Blood.”
