Mercedes Masohn has landed the female lead opposite Ben Whishaw in Alan Ball’s pilot for HBO All Signs of Death. Rounding out the cast are Ron Yuan, Jeremy Ray Valdez, Mahershalalhashbaz Ali and Kelsey Ford, who have joined previously locked Whishaw and Clayne Crawford. The dark comedic drama, based on Charlie Huston’s 2009 crime noir novel The Mystic Arts of Erasing All Signs of Death, centers on Webster Filmore Goodhue (Whishaw) an inveterate twenty-something slacker who stumbles into a career as a crime scene cleaner, only to find himself entangled with a murder mystery, a femme fatale and the loose ends of his own past. Masohn, repped by Greene & Assoc. & Luber/Roklin, will play Soledad Nye, a beautiful young Latina femme fatale who drags Web into a triple bucket of trouble. Ball is executive producing and directing the pilot, which was written by Huston. Filming is slated to start filming in Los Angeles later this month.
