Why did the original Gladys Kravitz leave the show?
Alice Pearce died unexpectedly of ovarian cancer in 1966. Similar to the way the Darrin switch was handled later, the new Gladys (played by Sandra Gould) was never explained. Whats more interesting is the fact that the first Louise Tate (Irene Vernon) left Bewitched willingly to pursue a different career. She became a real estate agent after leaving Hollywood. In what was probably the most easily accepted switch during the 8 years that Bewitched was on the air, Kasey Rogers assumed the role of Louise.
