King Conan: The Phoenix on the Sword
A little background: an idea I had was an anthology film that combines "The Frost-Giant's Daughter," "The God in the Bowl" and "The Tower of the Elephant," using "The Phoenix on the Sword" as a framing story. These are the first four stories Howard wrote, after all, and they show a pretty interesting spectrum of Conan's life: king, warrior, and thief.
"The Phoenix on the Sword" - 24 pages
"The Frost-Giant's Daughter" - 9 pages
"The God in the Bowl" - 19 pages
"The Tower of the Elephant" - 23 pages
Now, if we take the old "one page equals one minute" idea for a second, we can see that "The Phoenix on the Sword" and "The Tower of the Elephant" have roughly equivalent length, while "The God in the Bowl" is shorter, and "The Frost-Giant's Daughter" shorter still. Obviously depending on the direction this could expand or contract, but I think on can justify "The Frost-Giant's Daughter" as a ten minute sequence, "The God in the Bowl" a twenty-minute one, and "The Tower of the Elephant" as a full half-hour. While "Phoenix" is only a page longer than "Tower," it's absolutely chock full of potential for expansion, or just plain spending more time on it.
