DEVELOPMENT EXECS, take note. The comic industry has a new interloper in Philadelphia with the announcement that Blackball Comics will release its first slate of titles in March.

IN OKLAHOMA, the state film office has announced that reality television has returned to the Sooner State with crews from “Rescue 911” and “Unsolved Mysteries” shooting during the month of November.

In tapings coordinated by the Oklahoma Film Office, “Unsolved Mysteries” is in Oklahoma City to shoot an episode about an Arizona woman who discovered at the age of 52 that she was adopted and the discoveries she made searching for her birth mother, while “Rescue 911” is in Tulsa to tape an episode on the death of 15-year-old Brad Kaye.
