Between 1967 and 1972, Fox portrayed the witch doctor Dr. Bombay on 18 episodes of the sitcom "Bewitched". However, his first appearance on that show was not as Dr. Bombay, but as a professional witch debunker. He reprised the role of Dr. Bombay on the 1977 sequel series "Tabitha", and again in 1999 on the soap opera "Passions", and spoofed it as a genie doctor ("wish doctor") in a 1989 episode of "Pee-wee's Playhouse". Fox was the penultimate surviving adult recurring cast member of "Bewitched", leaving Nancy Kovack (who portrayed character Darrin Stephens' ex-girlfriend Sheila throughout the series) as the only remaining adult cast member upon his death; child actors Erin Murphy and David Lawrence, who portrayed Darrin and Samantha's children (Tabitha and Adam) are still alive.
