I only linked the ring to Tolkein on re-watching, thinking it was better to use Milton's Pandemonium than Tolkein's Orthanc (which I have discovered to be a quite respectable Old English word allied in meaning to the Greek polymechan which was one of Odysseus' labels. Cunning artificing.) But the scene did look like Orthanc in the films.

I hadn't linked the flame to Sauron's eye, though. I thought that waas the light on top of the Shard.
