For the love of Bengay,it looks like Big Brother will finally add a mature player (we’re talking septuagenarian here, people) to the cast when the show returns to CBS this Sunday. CBS is expected to reveal the entire cast tomorrow morning on The Early Show, but has already learned that a 75-year-old man (and ardent fan of the franchise) will be among the players vying for the $500,000 cash prize this summer. For a show that typically features 20-something hotties with gorgeous bodies, recruiting a great grandfather is a (welcome) first for the show.

“It’s the most diverse cast we’ve ever had in terms of ages, backgrounds, points of view, and personalities,” executive producer Allison Grodner says of the next installment. “Big Brother 9 involved couples, singles, and soul mates who were young, single, impulsive, and ready to party. We do a 180 with Big Brother 10. This summer you’re going to find a 22-year-old body builder and a 75-year-old great grandpa in the house, and everyone else in between. We’ve had diversity of age in past, but he’s clearly the oldest contestant we’ve ever had.”

For more from our chat with Grodner, check back with on Friday.
