In the original unaired pilot episode Ted Bessell's character was named Donald Blue Sky, not Hollinger. He played Ann's agent instead of a magazine reporter. During the episode he explains that his last name is from his heritage of being part Cherokee Indian. Harold Gould played Ann's father and Penny Santon played Ann's mother.
The name of the magazine that Donald worked for was Newsview Magazine.
Ann's apartment number was 4D.
The 1966 season theme song featured an instrumental version, which was subsequently replaced with lyrics.
The name of Ann's father Lou's restaurant was La Parisianne.
In the original unaired pilot episode, Ann and Don both work in the Seagram Building, 375 Park Avenue.
In the first season opening credits, Ann walks through Times Square and sees several Broadway marquees. "Philadelphia, Here I Come!" closed on 1 October 1966, while "Cabaret" opened on 20 December 1966 and Neil Simon's "The Star-Spangled Girl" opened on 21 December 1966. The three shows never ran at the same time.
The running gag of having the pre-credit sequence ending with a character referring to Ann as "that girl" was originally only supposed to be used in the pilot as it was believed that they would never be able to keep finding ways to work it into the conversation. It ended up being used in almost all the episodes.
Marlo Thomas' father Danny Thomas would often make cameo appearances on the show. One episode not only featured a cameo by her father but her sister Terre Thomas and brother Tony Thomas as well.
The final episode was originally going to have Ann and Donald getting married but Marlo Thomas (who was an executive producer of the show as well as the star) refused, claiming that it sent the message to young girls that a woman's main goal in life was to be married.
Ann's building is at 344 W. 89th Street. (Defiant One, Season 3).
According to Marlo Thomas, the relationship between Ann and her father, Lew, was loosely based on her real-life relationship with her father, Danny.
The train in the opening sequence of the series was shot at Secaucus Junction, in Secaucus, NJ. It was filmed out of the back of the train as it headed northwest, then the film was reversed, making it appear to be heading towards Newark. That is why traffic on the New Jersey Turnpike (running parallel to the right, with Laurel Hill in the background) is moving backwards.
One of the titles that was being considered for the show was "Miss Independent", which was the nickname Danny Thomas gave Marlo Thomas due to her independent spirit.
The title is from a quote in the Shakespeare play Romero and Juliet: "What's in a name. That which we call a rose, By any other name would smell as sweet."
The title is based upon the expression: "Don't just stand there, do something!"
The title is based upon the 1938 song "I'll Be Seeing You" written by Sammy Fain and Irving Kahal.
The title is based on the 19th English counting rhyme: Tinker, Tailor, Soldier, Sailor, Rich Man, Poor Man, Beggar Man, Thief.
This episode introduces the recurring character of Jerry, played by Bernie Kopell.
The title is based upon the comic strip character Little Orphan Annie created by Harold Gray in 1924 which has also been in books and comic books, on radio and television, in the movies and produced for a Broadway musical.
The title references a theater term spoken to performers going on stage. The theater superstition that wishing someone good luck is considered back luck, thus a negative remark should bless the performer with good luck.
This is a revised version of the test pilot. About half of the footage shown as the pilot is reused, only adding new footage where different actors are playing different parts.
The title is from a quote from the Shakespeare play Romero and Juliet: "What's in a name. That which we call a rose, By any other name would smell as sweet."
The title refers to the song "Smoke Gets in Your Eyes" written by Jerome Kern and Otto A. Harbach for the musical Roberta.
Donald writes a story for Newsview magazine about Ann's eccentric neighbor; the issue that the article appears in has the same exact cover (a picture of a NY bridge) as a later episode in which he writes a magazine profile of Ann (All About Ann).
The title is based upon the novel The Phantom of the Opera by Gaston Leroux, which has been used for many plays, movies, musicals and operas.
