AVClub: Movie biographies tend to turn on epic, stunt-like impersonations of famous figures by other famous figures. Elvis & Nixon performs the ritual of stunt-casting impressions twice, and with such looseness that it almost plays like a spoof. Liza Johnson’s film purports to tell the story behind the famous photograph of singer Elvis Presley and President Richard Nixon, taken a few days before Christmas in 1970, but the historical record doesn’t offer all that much to work with. Frankly, the ahistorical non-record doesn’t really support a feature film, either. Elvis & Nixon’s play-by-play of the eponymous figures and their underlings negotiating and carrying out Presley’s impulsive, unsolicited visit stretches its 86-minute running time thin.
