Gary Cooper was originally chosen to portray Tom Dunson - ultimately played by John Wayne, but refused on the role because of the character""s ruthlessness and contemptibility.At that moment, Emperor Han (with support from General Yang) attacked them in Shangri-La, and as he seized the dagger, the terra-cotta covering broke free from his restored body.Also present was the powerful leader of the militant, animalistic Brotherhood of Mutants - embittered Magneto (Ian McKellen), Xavier""s ex-ally (and Holocaust survivor Eric Lensherr with a number burned into his arm) who could create magnetic fields and control metal.The outrageously crazy Moody taught his students an illegal lesson about the three Unforgiveable Curses, including the Imperius Curse (when a victim was forced to do another""s bidding), the Cruciatus Curse (aka the Torture Curse), and the third - the Killing Curse ("Avada Kedavra") - survived by only one person, Harry Potter." He labels his own torture methods as "absurd and unpleasant extremes." His favorite and most effective method of torture is to drive bamboo slivers beneath their finger-nails and light them.
