Tanya Roberts has confirmed in an interview that, shortly after she arrived, she was sent her to have her brown hair dyed red.
"Angel in Hiding" (as two hourlong episodes) and "To See an Angel Die" were all broadcast as a three-hour Angels marathon the evening of the season five premiere on November 30, 1980.
In close ups, it can easily be seen that Tanya Roberts is wearing turquoise blue contacts: the outlines of her contacts show in the whites of her eyes.
The same distinctive white bikini with pink and blue stripes that Louise (Katherine Moffat) wears while promoting microwave ovens at the home show is worn by a woman lounging by the pool at Julie's apartment complex when Kelly arrives to question her.
