How could they say that the Witch was not afraid of Aslan in the movie? At the first mention of his name by Edmund you could see the look in her eyes as she looks toward the dwarf. And how about when Aslan growls at her and she sits quickly down like in the book? She was clearly in fear of him and the only thing protecting her was her "claim" on the traitor Edmund.
