The essential motivation to see “Elvis and Nixon” is for seeing two awesome on-screen characters going up against a challenge.
Kevin Spacey as Richard Milhous Nixon? Without a doubt the part is the karmic opposite of Frank Underwood, the deadly fox of a president the performer plays on Netflix’s “Place of Cards.” And Michael Shannon as Elvis Aron Presley? No. Just… no. But that Shannon motivates you to consider yes, even with those eyes that blast derangedly where Presley’s tops hung. This is Elvis as he may exist still in a parallel universe, one where he gives orders rather than the Colonel and where a wacked-out hero can be a switchblade of vitality as opposed to an inactive wreck.
