Some differences between the first season and the remaining seasons: the theme song is sung by The Peppermint Trolley Company (by the Brady kids thereafter); some background/scene music is different and only heard in the first season; Florence Henderson (Carol) wears a wig; Maureen McCormick (Marcia) wears pigtails.
F-f-fil,l-l-lmo, o-o-ore, Fillmore Junior High!
The series never shows Alice having her own bathroom. The house clearly must have at least 3 full baths for the nine people who live there as it would be very difficult for Alice to use the children's upstairs bathroom and very unlikely that Brady parent would allow her to use their master bedroom one. However, in the five year run of the program, Alice's bathroom is never shown although her rather tiny maid's quarters are several times.
The nine cast members are shown in a tic-tac-toe format, with the actors turning their heads to look each other.
In 2001, VH1 aired a series of episodes with information bubbles on the screen in the style of _"Pop Up Video" (1996)_. These episodes were collectively identified under the title "Pop-Up Brady".
