Casting for Big Brother 10 began on February 25, 2008. Applications were due on April 25, 2008 and video tape submissions were due on April 4, 2008. During May 2008 interviews for the 40 semi-finalists were held with the finalists being chosen on May 21, 2008. Casting calls were held in various cities across the country including Los Angeles, California, Charleston, South Carolina, Louisville, Kentucky, Minneapolis, Minnesota, Pittsburgh, Pennsylvania and Phoenix, Arizona. Big Brother 8 winner Dick Donato announced on House Calls that Big Brother 10 will feature a wider range of HouseGuests. E4 will not air Big Brother 10 as they did with Big Brother 9 due to conflicts with the ninth edition of the British version. A live audience is present during the live eviction episodes on Wednesdays. Beginning July 31, the live eviction episodes moved to Thursdays. This is the first time since Big Brother 1 that an audience will be present for the live weekly eviction shows.
