The film began as a story called
Hollywood Starr, about a girl who, abandoned by her father, becomes a prostitute. She has to deal with a serial killer dressed as Santa who turns out to be her father. The story was written in treatment form by Robert Vincent O'Neil, author of
Vice Squad, and Joe Cala. They—which was originally just a treatment—impressed producer
Sandy Howard who enlisted Don Borchers to produce. Borchers said Howard was inspired by the poster for the film
Tootsie which showed
Dustin Hoffman as a man and a woman; he wanted to show the lead character as a student and a prostitute on the poster. Most of the film was shot at real locations on and around Hollywood Boulevard. Borchers said that Wilkes and
Cliff Gorman did not get along, due to a conflict that originated during the taping of a pilot for the sitcom
Hello, Larry on which both were cast. Gorman would tease Wilkes about her height and she would mock him for his glass eye; this cumulated in Gorman chasing Wilkes until she ran to her dressing room and he smashed the door in. Gorman was fired from the sitcom, replaced by
McLean Stevenson. The producer said the film cost around $1.5 million and was sold to
HBO for $4 million, in part because of the recent ratings success of the television film
Little Ladies of the Night on
NBC. O'Neil said Wilkes "was just terrific to work with", but she was not cast in the sequel because "her agent was asking an outrageous price and pissed Sandy off and he wouldn't even talk to them" so he cast Betsy Russell who "did not have the vulnerability that Donna has... That's what was missing, you know. So
Avenging Angel was not the film
Angel was, unfortunately." O'Neil recalled, "I used two cameras every chance I got. Almost all scenes with Dick Shawn because I couldn't get him to do a scene the same way twice. With him it was like catching lightning in a bottle. I learned that the first day of shooting with him." Borchers said in the original cut of the film Rory Calhoun's character was supposed to die. However, test audiences did not like the ending where Angel killed the serial killer, so scenes were added where Calhoun's character returned to shoot the killer. The film premiered at the
Hollywood Pacific Theatre on Hollywood Boulevard. A fact sheet inside the theatre, prior to its closure in 1994, confirmed this. The theatre is also featured in the climax of the film, when a gun-toting Angel opens fire on the killer and terrifies the patrons outside. ==Music==
