The Exorcist author William Peter Blatty’s house, up for sale for $27.5 million, might make your head spin around when you see it. The gated three-acre Hidden Hills estate called Old Lion Manor that Blatty lived in for 10 years has a movie theater that seats 28; a tennis court; volleyball court; equestrian ring and horse stables; spa with massage room and tanning booth;  gym; wine cellar with tasting room; outdoor chessboard with giant pieces; mechanical bull; and a free-form swimming pool with waterfall, grotto, and swim-up bar.

The house has six bedrooms and 11 bathrooms, one of which features 10 urinals. Pee soup with envy?
