“Casting By”
Premieres: Aug. 5 on HBO
Why It’s Worth Watching: Casting directors rarely get the praise they deserve. Just ask them. Tom Donahue‘s documentary, however, focuses on pioners like Marion Dougherty and Lynn Stalmaster who trusted their gut instincts to reject traditional Hollywood casting in favor of bringing new kinds of leading men and women to the screen, like Dustin Hoffman, Bette Midler, Robert Duvall and Gene Hackman.
