And once I determined that the home was located in a gated community, the other part of the 90210 pilot house mystery was solved, too. Upon entering, I just happened to ask the guard on duty at the guard shack if the community allowed filming of any sort to take place on the premises. He told me that in fact filming is not allowed and he laughed as if he gets asked that question all the time. I am sure location scouts come a-knockin’ at the guard shack door all too often. My best guess is that back in 1990, when the pilot episode was filmed, there was no ban on filming in the neighborhood. The pilot house was probably the first home on the premises ever used for filming of any sort. And I am pretty sure it must have belonged to someone on the production team – ie. the director, producer, art director, etc. It actually happens more often than you’d think that someone involved with a lower budget production will offer up their home for filming to keep costs down. Because the Pilot House is a beautiful home located in an upscale community, and since the 90210 pilot budget was most likely quite small, I think that is exactly what happened. Otherwise I just don’t see how they could have afforded to film there. If you’ve seen the pilot episode as many times as I have, you’ll remember that most of the location shooting at the Walsh house took place at night, which I am sure angered quite a few neighbors. Night shoots usually last from sunset to sunrise and can be loud, messy, and annoying to anyone whose house is nearby. So I am gonna go out on a limb and say that during the production of 90210, a few of the neighbors probably got a little miffed about the filming and as soon as the pilot wrapped, members of the small community (there are only 67 houses on the property) made certain nothing like that would ever happen again. So when Beverly Hills, 90210 got picked up as a series three to six months later, the producers were left without a home to use for filming. And that’s how we ended up with Casa Walsh. 🙂 here
