Personal Information - Because they were not very aware of what could be said inside the house, the participants released crucial information about their lives outside the home. Kléber Bambam had already made figurations in Globo shows, such as Zorra Total, and was once a dancer from "Planeta Verão", a program led by Xuxa Meneghel. André Gabeh had also sung on a Xuxa program years before. Helena Louro had already participated in a film with Gracindo Jr. (The Hour Marked, 2001) in which she gave sexual favors to him in exchange for advantages. Vanessa Pascale and Bruno Saladini had also appeared in fashion catalogs and worked in the same modeling agency, as did Helena. Leka had already given interviews on the Amaury Jr. program, then at Rede Record
Two Presenters - The BBB1 was the only one that started with two presenters: journalist Pedro Bial and actress Marisa Orth. The departure of Marisa Orth is due to the inexperience of the actress as presenter, marked by a gaffe committed live on February 2. In this program, the leader of the week, Sergio, should indicate who would go to the "wall". Marisa announces, before the participant itself, that Caetano was the one indicated, leaving the leader in skirt fair. In order not to suddenly disappear from the program, Marisa Orth would appear on the big screen every Friday to talk to her competitors, as a kind of psychologist, taking away some confidences from the residents.
Shorter Season - With 64 days of confinement, it is the shortest season of Big Brother Brazil.
