On the heels of a recent study that said Native Americans are virtually invisible on TV, CBS is making a bold move toward diversity: The Eye will sponsor a Native American acting showcase on Oct. 9 in L.A., with CBS execs and casting directors present to check out the talent. Aspiring thesps can submit headshots and resumes from Aug. 12-Sept. 6 to: David Besbris, CBS Showcase Submission, c/o AFTRA, 5757 Wilshire Blvd., 9th Floor, Los Angeles, Calif. 90036.
