But in fairness to Tilda Swinton, she was reported to be a great trouper on the production location, constantly looking out for fellow performers and keeping up their spirits with her good humor.
The BBC's witch was fantastic. Frightening and beautiful. The Disney witch was too ... gaunt. Not scary, just ... like something was wrong with her. She also was NOT beautiful, and Jadis/the White Witch/etc. was/were gorgeous as well as terrifying.
(I'm not sure which witch is Tilda, but that's my two cents' worth.)
