The mansion belonged to a silent movie star who's life was very similar to the main character in The Artist. I won't spoil the movie, in case you haven't seen it. His story also sounds a lot like The Great Gatsby, but maybe that's because his wife was named Daisy. They split and she died tragically on Mulholland Drive. Some people think that there was foul play and speculate that this might be why the house is haunted.
Some famous very bad rock bands have stayed and recorded here and claim to have seen and experienced all sorts of freaky things... being chocked in the night and bathtubs filling with water.
I can say that it was kind of eerie at first. There were some freaky angel and devil paintings and taxidermy everywhere. The souls of all of the poor African animals! Overall though, I've been in places that are much creepier. The only bad vibrations that I felt were coming from the guy who owned/ managed the house. Perhaps all of the bad spirits attached themselves to him. He was so rude that you had to laugh and play along.
The courtyard - also where they filmed a Brittney Spears video where a car goes into the pool??
This room was my favorite. Windows on all sides. (unfortunately some kind of rare taxidermied Toucan on the coffee table... oh and a stuffed peacock on the long table.) Click to see bigger
Just happen to have a triceratops head in the study. Shot and killed that beast myself, that's right.
