Housemates Kitten, Marco, and Victor all appeared on the spin-off series Big Brother Panto in 2004, For the first time ever, housemates were selected via open auditions rather than via home video.
Whilst in the Bedsit, they had a live feed of the house, which aired in the room non-stop for their viewing pleasure.
They were granted access back into the house after five days.
Promoted as "Big Brother goes evil", Big Brother 5 saw numerous changes occurring to the game.
The main twist this series was that the grand prize had been increased to £100,000 for the winner, but was gradually taken away as the series went on based on Housemates' performances in various tasks.
The latter programme returned in subsequent series under a retooled format and was renamed Big Brother's Big Mouth.
