Elwin Ransom
Elwin Ransom may be based on C. S. Lewis' friend J. R. R. Tolkien ("Elwin" means "Elf friend" in Anglo-Saxon), though he seems to have autobiographical elements. In "That Hideous Strength" Ransom, with his royal charisma and matter-of-fact breezy acceptance of the supernatural, appears less like Tolkien than like Charles Williams (or some of the heroes in Williams' books).
Tolkien family
Simon Tolkien notably disagreed with the policy of his grandfather's estate in regard to "The Lord of the Rings" films. When Christopher Tolkien issued a statement that the "Tolkien estate would be best advised to avoid any specific association with the films", Simon Tolkien broke ranks, offering to cooperate with the filmmakers, stating "It was my view that we take a much more positive line on the film and that was overruled by my father." Following up a 2001 interview with the "Independent", Simon in 2003 gave interviews to the "Daily Telegraph" and other media in which he discussed his strained relationship with his father, describing it as a permanent breach. However, they have since reconciled.
