Four unnamed people who look and sound a lot like Albert Einstein, Marilyn Monroe, Joe DiMaggio, and Joseph McCarthy converge in one New York City hotel room for this compelling, visually inventive adaptation of Terry Johnson’s play, from director Nicolas Roeg (Walkabout, The Man Who Fell to Earth). With a combination of whimsy and dread, Roeg creates a fun-house-mirror picture of cold war America that questions the nature of celebrity and plays on a society’s simmering nuclear fears. Insignificance is a delirious, intelligent drama, featuring magnetic performances by Michael Emil (Tracks, Always) as “the professor,” Theresa Russell (Bad Timing, Black Widow) as “the actress,” Gary Busey (The Buddy Holly Story, Lethal Weapon) as “the ballplayer,” and Tony Curtis (Sweet Smell of Success, Spartacus) as “the senator.”
