Clint Eastwood tells us how he yearned to be a director from the time he was on “Rawhide” to finally obtaining the approval of his mentor, Don Siegel. He then asked Lew R. Wasserman, a Universal executive, if he could direct a story called “Play Misty For Me.” Lew said yes but that he wouldn’t be paid as the director. Clint agreed and began to locate the cast and crew he desired.
