The next round of CBS' Big Brother, likely to premiere in early July, will be an "all-star" edition in which fans can vote from a pool of 20 past players to fill the household's 12 to 14 openings. "This will be the most interactive Big Brother yet," exec producer Allison Grodner tells Variety. "Viewers will be involved more than in the past." Fine, but anyone who votes for Holly and her annoying voice will hear from me.
