This young, theater-loving group of theater people, led by three siblings with the last name of Dawson, made a big splash in late 2009-10 at the well-appointed theater at the OC Pavilion. But after that venue was sold to the Orange County High School of the Arts last summer, 3-D needed a new home. It found one at Fullerton's Plummer Auditorium. The Fullerton Civic Light Opera had produced theater at the space for four decades, but the recession crippled that entity, and it had to vacate the Plummer. Then 3-D Theatricals stepped in and produced the 2011 season, saving ticket subscribers a boatload of aggravation. The shows were your typical mainstream fare, such as The Drowsy Chaperone and the upcoming The Wizard of Oz. It looks like there's more of the same in 3-D's just-announced 2012 season, but it has added a youthful injection of energy with Avenue Q and Hairspray.
