Big Brother: All-Stars is the seventh season of CBSâ€™ landmark reality television series Big Brother. Returning host Julie Chen once again opened the door to the Big Brother house, but this time the contestants were notable personalities and fan favorites from previous seasons. The fourteen contestants were chosen by both the producers and by an Internet fan vote. The Big Brother house theme was â€œA House of Extremesâ€ which was illustrated in the neon flames, gargoyles, and even tarantula cage that could be found throughout the house. Also included in the dÃ©cor were notable items from previous seasons, which hung on the wall. Season 7 of Big Brother introduced the Emmy Award-winning feature â€œBig Brother Goes Mobile,â€ which gave viewers an all-access pass to the houseguests and show extras for a small fee. The showâ€™s internet review show â€œHouse Callsâ€ returned for another season of interviews. Big Brother: All-Stars aired in 2006.
