Home theaters with comfy seating and a movie screen or an oversize flat-screen TV are old hat. This estate in a gated community overlooking a country club features a full-on theater with a stage big enough for a grand piano. With Hollywood nearby, you never know when an entertainer might drop in.
Whoever does come by can enjoy a full bar and lounge area for pre-concert gatherings, and separate guest quarters if the show runs late.
