Vappu Pimiä was the host of the Big Brother Talk Show and Jani Toivola hosted Big Brother Extra. This was the last series where Pimiä served as a hostess; the fifth season was the only series in which Toivola appeared.
The open auditions for the series were completed in April 2009.
Rich and Poor House: The twist of the season revolves around the division of the house where in the main house is called Paradise while another poorer area is called the Slums. Housemates in Paradise get to live in the main house, have hot water 24/7 for bathing, plentiful of food and the power to nominate. Housemates in Slums get to live in a makeshift area, sleeping on the floor with their jackets as blankets, a garden hose to wash themselves in a roofless toilet, limited food (rice, sardines, porridge and pea soup).
Head of House: The concept of having a Head of House was first introduced in this season. Each week the housemate will compete in Head of House competitions where the winner will gain immunity as well as having the power to designate which housemates would stay on which side of the house.
