"One of our editors... found some Polaroids from 1977 that showed a large excavation project at The [Playboy] Mansion."

"We asked the new general manager at The Mansion about these photos. He said, very matter-of-factly, 'that�s probably when they built the tunnels in the 70s.'"

So, according this blueprint, tunnels were built to the homes of �Mr. J. Nicholson,� �Mr. W. Beatty,� �Mr. K. Douglas� and �Mr. J. Caan.� We�ll go ahead and assume they�re talking about Jack Nicholson, Warren Beatty, Kirk Douglas and James Caan � all of whom lived near the Playboy Mansion during the late 1970s and early 1980s. There are no dates on the architectural schematics, but the dates on the Polaroids were from 1977.
