Have you ever watched the 1925 version of Ben-Hur: A Tale of the Christ? Of the three full-length film adaptations of Wallace's novel, it certainly follows the text the closest, including subplots and parts of the text that the others chose to omit.
Like Andrei Rublev, I've wanted to see the 1925 Ben-Hur for years, but I haven't been able to find a decent copy of it anywhere. Would you say it's better than the '59 version?
The 1925 Ben-Hur was released on blu-ray over ten years ago so it shouldn't be too hard to find a decent copy, especially compared to most silent films.
