I've cut back the claim to mention just a process shot (according the Oxnard Convention and Visitors Bureau), since the city of Shangri-La, which was a set built on a backlot, couldn't have been shot from above Ojai.  But in order to claim that the connection of Ojai to Lost Horizon is only a legend, we would need to locate someone reputable (not a WP editor or some unnamed person that a WP editor spoke to) with that POV, and I haven't been able to find such.    

 :The Oxnard bureau site reads more like a promotion for the Inn, and indeed my own Googling came across that same body of text on at least half a dozen sites. While it stands as an example of an apparently credible source, it's still no more a primary source than anything else I've managed to come across online. Mind you, I'm not out to disprove the claim, I'm just 1) astonished that I've actually met someone who disbelieves it/claims it isn't true and 2) subsequently decided that what's needed is verification of a primary source to cite; ideally a quote or document attached to the production itself.   

  

 I reorganized the way some of the information has been laid out. The Lost Horizon information was under the Film and Music heading, yet the other information under that heading pertains to film-and-musical related activities and events that are characteristics of the town, while the heading Fiction recounts exclusively mention or appearance of the town in films. 
 It seems more logical, perhaps, to rename the Fiction heading and include the Lost Horizon item with other "appearance in film" type items.
