There are many more fun tidbits one can learn during the two-hour tour, but we'll leave something for tour guides to tell. Cats were brought in to solve the rodent problem and now the cats have been known to scratch and destroy set pieces - just ask Ellen. The first reason is to prevent dusty set pieces, but the second reason was more interesting: cats! There is a cat problem on the Warner Bros. Kourounis took us inside and we sat in the audience as he explained how TV magic is made.įun fact: He told us why sets are covered during filming breaks. Maybe it's the set of 'The Ellen DeGerenes Show' or ' Pretty Little Liars' or maybe… ' The Big Bang Theory.' Interest and what shows are not filming will determine where the tour guide will take you. One of the best parts of the tour was visiting a soundstage, in which no photos or videos are allowed.
