[If monetary incentives are minimal, what are our other appeals?] What we try to sell, ... is the quality of our crews, the ample availability of our services for catering, equipment rental, security and police cooperation. A major asset is our population of over 3,000 members of the Screen Actors' Guild, third biggest in the U.S., that can enable studios to cast many parts locally. With Steppenwolf and others, we have an exceptional talent pool. Last, they're breaking ground on a new ultramodern studio with five sound stages, on West Roosevelt Road. Brenda Sexton
