Big Brother 1 (UK)

Big Brother 1 is the upcoming first season of the UK edition of Seth's Big Brother. It is set to begin in March of 2013, featuring a total of six Housemates. They will be competing to win the series, which will last for a total of twelve days.

Development
While working on the US edition of the series, Seth expressed interest in branching out the series into a new version based on the UK format. While working on the third edition in the United States version, it was announced that the UK series would begin after the conclusion of Big Brother 3. Though it was slated to last for a total of 30 days, it was cancelled on the fifth day, with Seth stating he didn't enjoy hosting the series anymore. Despite stating he would take time off from hosting, he later announced that he would begin working on the UK version of Seth's Big Brother. He later stated, "I enjoy hosting, I'm just not sure when the best time for me to continue hosting is. So, I'll be doing a short version of Big Brother UK, and that will determine if I continue hosting or take a hiatus." He has since stated that he will most likely continue with this version rather than the US version, stating "With the UK format, there's more freedom in terms of twists and changes, and I think it will be a lot of fun for both me and the Housemates."

Initially, the series was slated to last for ten days, before being expanded to eleven and then twelve. Seth stated that he felt the two extra days would make the game go by smoother, and allow for more events to occur. Unlike the last US edition, Seth is working on the series alone, and there will be no co-host. He has, however, expressed interest in working with Gil and Matt again in terms of selecting Housemates for the series. In terms of twist, the game will not stray too far from the main format, and Housemates will still select two Housemates to be up for eviction, with the public deciding who goes. There will be a total of three Housemates remaining at the finale, with three evictions occurring beforehand. Seth also confirmed that tasks would be a part of the game as well, though they would be for a different prize each week. Seth later stated that he is most looking forward to evictions, in which he will interview the evicted Housemate about the game. The series is set to begin on March 1, 2013.

Casting
Casting for the series began on February 22, 2013. This first round asks basic questions about an applicant. The second round featured more in depth questions about an applicants playing style and other information about what kind of a HouseGuest they would be. The third and final round confirms some of the mechanics of the game with the applicants, and they must agree to these terms. Unlike the US edition, the cast will be revealed one at a time during the premiere, much like the televised version of the series. In total, there will be six Housemates.

Format
Big Brother is a game show in which a group of contestants, called Housemates, live in isolation from the outside world in a custom built "house", which includes everyday facilities such as a fully equipped kitchen, garden, two bedrooms, and a bathroom. The only place where Housemates can escape the company of the other contestants is the Diary Room, where they are encouraged to voice their true feelings. Each week all housemates nominate two of their fellow contestants for potential eviction. Failure to do so may result in a punishment, such as expulsion. The two, or more, Housemates with the highest number of nominations face a public vote conducted by poll, with the contestant receiving the most votes being evicted from the house. The last contestant remaining in the house is declared the winner. On eviction night, there were two live eviction shows held. In the first, host Seth would reveal to the Housemates who had been evicted from the house, though the percentages were withheld from the group. Following the announcement, the evicted Housemate had two hours to prepare to leave the house. At the start of the second episode, Seth would inform the evicted Housemate that they had only moments to walk out the door. Upon exiting through the house's front door, Seth had an interview with the evicted Housemate, and discussed their best moments in the house, as well as some interesting points of the show. Over the duration of the series, the Housemates are given a series of tasks by Big Brother which test them in many ways. They are also put to the test by their own ideals, prejudices and opinions against other people from different walks of life; something that has survived from the original "social experiment" of Big Brother. Housemates must also live by the fundamental rules of Big Brother; if the rules are broken it can result in formal warnings, various punishments or even a Housemate's removal from the House. Each week Big Brother sets the Housemates a task in order to determine various aspects of the game. Some tasks will be for Immunity, while others will simply be for fun. They must work together to win the tasks in order to win the prize.Each night, the housemates were also given a discussion topic, and they would have group discussions in the living room.
