The show was cancelled during its first season. It was brought back the next year after fans staged a letter-writing campaign.
The character of Andrew was supposed to be on for only two episodes, but proved to be so popular, John Dye had received a starring role, towards the end of the second season.
According to an interview with Roma Downey, many of the clothes Monica wore in the first season were Downey's. She wore such a small size, the wardrobe department didn't have anything that would fit her.
John Masius created the first pilot for the series, but it was a darker, less hopeful story than the producers wanted and cost the studio $2 million to produce. It was meant to focus on suffering's existing due to a cruel sense of humor by God, and showed Tess as a chain-smoking angel who was frequently at Monica's throat. (Della Reese once said in a interview that in it Tess was mad at Monica because she owed her $400.) Masius wrote the show as a reflection of his spiritual anger at the time at his two children being born disabled. Martha Williamson was approached to be the series' executive producer in early 1994. She described the pilot she received as "upsetting" as it "portrayed angels as recycled dead people with power over life and death". She initially declined the position, but during a lunch with Andy Hill, then President of CBS, she mentioned the show and suggested he find a producer who would create a show with "loving, joyful" angels that the audience would have to believe in.
For most of the series' run, Tess drove a 1972 Cadillac Eldorado Fleetwood. On occasion, Monica would be driving the car, though Tess gave her the car, on the series' finale.
