@Courtenay It was actually a living thing that grew from the soil — the version of it in the Walden film of LWW even has roots at its base, so somebody on the design team must have read MN as well! — and so it must have had its own capacity to produce light. Maybe, just as ordinary plants take in and store energy from the sun through photosynthesis (which is how they make their own "food"), the living Narnian lamppost took in and stored up solar energy to power its own light! Makes sense to me.

But would a Greta Gerwig version be able to use Walden's designs for the Lamp Post? I'll have to watch the film again to see that bit. Meanwhile I'd be wary of Uncle Andrew's likely reactions to the planting of the Iron Bar. You wouldn't want people like Uncle Andrew getting ideas about that sort of thing. It's bad enough that we have a whole airport being built to be run with solar power.

Most likely not, unless she made some special arrangement with the past director and artistic designers and so on, and I don't see why an all-new director of an all-new adaptation would really want to do that, especially when there's no need for it. I just thought that was a clever little twist in that particular film.

I'm slightly baffled as to why a whole airport being run with solar power should be a "bad" thing compared to running it with other power sources, but this isn't the place for political debates, as we've been reminded recently. Regardless, Uncle Andrew of course DOES get ideas about the planting of the iron bar, when he sees it's grown into a lamppost...

"The commercial possibilities of this country are unbounded. Bring a few old bits of scrap iron here, bury 'em, and up they come as brand new railway engines, battleships, anything you please. They'll cost nothing, and I can sell 'em at full prices in England. I shall be a millionaire...." (p. 103 in my edition (Puffin))

But Aslan later confirms, when Polly mentions Andrew's ambitions, that this won't actually work:

"He thinks great folly, child," said Aslan. "This world is bursting with life for these few days because the song with which I called it into life still hangs in the air and rumbles in the ground. It will not be so for long. But I cannot tell that to this old sinner, and I cannot comfort him either; he has made himself unable to hear my voice...." (p. 158)

@ Courtenay  Regardless, Uncle Andrew of course DOES get ideas about the planting of the iron bar, when he sees it's grown into a lamppost...

Uncle Andrew wasn't the only one who ever went gaga over machines etc & who dreamed of becoming a millionaire, or who has attempted any get-rich-quick schemes. The real-life ones are infinitely worse, when, like Susan, I'm none too keen on gambling.

That depends on how well it runs when it is finished. And that we have yet to see, next year.  

I'd be opposed to Netflix using Walden Media's design for the lamppost even though I love the roots idea. I feel like trying to make the new version of Narnia feel like the same one as in the 2000s would be (a) a burden on the filmmakers and (b) unlikely to succeed anyway. Maybe it'd be different if The Lion, the Witch and the Wardrobe (2005) were a really old classic that the new filmmakers grew up watching and loving. Then it might be fun for them to try to recreate its world.

I don’t know why they would use an exact replica of the Walden movie’s lamppost for the Netflix film unless it would be because they couldn’t think of a design of their own. Since it is a new series of films they should probably create a new design of their own. I am not overly fussy about something like that. It is only a prop which should be much like the one in the original story.  I just think it should fit in the Victorian time period and with the creation of Narnia. The same lamppost could probably be used again for Greta Gerwig’s movie The Lion, the Witch, and the Wardrobe. The best lamppost would work well for both our world and Narnia.
