Elvis & Nixon details the surreal saga of how Presley, concerned about drugs and anti-war demonstrations, flies to Washington on a whim and delivers a handwritten letter to the White House, requesting a meeting with Nixon.
IE caught up with Colin Hanks, who plays a presidential adviser, during the film's premiere at the Tribeca Film Festival.
"You just want to know how on Earth that happened, because it just shouldn't have happened," the actor told us.
Presley wanted to be deputized as an undercover narc, he wrote to Nixon. He also wanted a badge.
