The beach outdoor scenes in Captain Blood where filmed in Laguna Beach. This area was used by Warner Bros for a lot of their beach scenes. e.g. look at Now Voyager when Davis and Henreid are having their first lunch together and there is a view of the ocean. Same location as the Rathbone \ Flynn sword fight in Captain Blood. (one can tell by the rocks out in the water).
I'll be going to this same spot later today for a swim. Those rocks are still there of course but sadly Olivia isn't!
That's great, James. What I was trying to underscore with Ian is that sometimes they have outdoor shots (such as retakes) that are done on the backlot. And often the exteriors are stock footage used in rear projection shots. I think PLYMOUTH ADVENTURE had a lot of that. And probably if you look closely at scenes in CAPTAIN BLOOD, though they have long shots filmed in Laguna, they still cut to close-ups filmed on stage or on the backlot. They have to do that usually because of sound problems on location. And if they use the on-location footage, chances are the dialogue has to be dubbed because of the wind, a plane flying overheard or crashing waves that might have drowned out the actors' line deliveries.
But the real issue is that when Ian sat down to watch THE BUCCANEER '58, he came to it with notions of how these kinds of movies are supposed to be made (according to him)...and I think if you do that, you miss out on the artistry that can still be achieved if most of it is done at a studio or on the backlot. With THE BUCCANEER '58, and this is the sense I get with the stuff Heston wrote in his autobiography (which Ian read on camera)-- Quinn's focus was on performance and the theatrical aspects of telling the story, as opposed to making it a pseudo-documentary about the War of 1812 and its historical figures.
A good analogy would be to look at westerns. Just because something isn't entirely filmed at a ranch with characters on horses going down winding trails all the time doesn't mean the film can't still evoke the feeling of a western, shot on sets built on a soundstage. That's where the artistry comes in, in terms of production design, direction and performance.
