Beverly Hills, CA -- It was a very Brady reunion for television critics yesterday at HGTV’s TCA panel, as the network presented original Brady Bunch cast members Maureen McCormick (Marcia), Eve Plumb (Jan), Susan Olsen (Cindy), Mike Lookinland (Bobby), Christopher Knight (Peter) and Barry Williams (Greg) to promote their much-anticipated unscripted limited series A Very Brady Renovation. In the series, debuting September 9th, the original “Brady kids” ably assist some of the network’s biggest design and renovation stars as they undertake the mammoth task of completely overhauling the iconic Studio City house (used only for exterior shots in the original Brady Bunch series) into an exact replica of the home they shared on a Paramount soundstage – complete with Formica countertops, retro fabrics, shag carpets, Jack and Jill bathrooms, fondue pots and more. For many of the cast, it was the first time they’d ever stepped foot in the actual house, and even though it is one of the most photographed houses in America (reportedly second only to the White House). “[While filming] we didn't know where the house was,” Knight admitted. “I didn't learn where it was until 1996!
