Insignificance is a 1985 British alternative history drama film directed by Nicolas Roeg, and starring Gary Busey, Michael Emil, Theresa Russell, Tony Curtis, and Will Sampson. Adapted by Terry Johnson from his 1982 play of the same name, the film follows four famous characters who converge in a New York City hotel one night in 1954: Joe DiMaggio, Albert Einstein, Marilyn Monroe, and Joseph McCarthy—billed as The Ballplayer, The Professor, The Actress and The Senator, respectively.
