With two upcoming high-profile roles — in Snow White And The Huntsman, due on June 1, and Prometheus, due one week later — Charlize Theron is being honored in Las Vegas by CinemaCon with its Distinguished Decade of Achievement in Film Award. The honor will be handed out April 26 at the theater owner’s convention’s awards ceremony. Theron, a new mother on top of everything else, is coming off some of the best reviews of her career in the 2011 dramatic comedy, Young Adult. She won a Best Actress Oscar for 2003′s Monster, in which she played against her looks by playing Daytona Beach prostitute Aileen Wournos, who became a serial killer. The CinemaCon convention is the annual Las Vegas meeting put on by the National Association of Theater Owners.
