A theological issue of ancient and significant import

In debating the issue of whether the Spirit proceeds from the Father only, or from the Father and Son equally, the Empire was severed and the ancient Church schismed.

At the risk of evoking a question as troubling and profound, I must ask, first, if you were a SF writer whose book was about to me made into a movie,  which would you think was more Way Cool:

To be Neil Gaiman author of STARDUST, which gets Michael Pfiffer to drive a chariot pulled by goats?

Or to be Peter S. Beagle, author of THE LAST UNICORN, with a chance of getting Christopher Lee to reprise his role as King Haggard?

I remember the day, not so long ago, when it was seriously argued that the American public would never want to go see a Fantasy movie.
