Insignificance is a 1985 British alternate 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. Plot On a crowded New York City street, people have gathered to watch a film crew shoot a sequence where The Actress in a white dress is standing on a grate while the rush of wind caused by a huge fan to imitate the subway going by below blows her skirt up around her waist. The Actress's husband, The Ballplayer, watches with obvious discomfort as she is ogled. The Actress, rather than join him afterwards, disappears in a taxi, leaving him behind. She stops at a store and picks up a variety of toys, flashlights, and balloons. Meanwhile, The Professor is in his hotel room, working on pages of mathematical calculations. He is interrupted by The Senator, who has come to alternately coax and threaten him into appearing before a committee to investigate his activities and answer the famous question, "Are you now or have you ever been...?" The Professor refuses and says he will never appear. The Senator leaves, saying he'll be back to get him at 8 a.m. the following morning. The Actress appears at the door of the Professor's hotel room, and he invites her in. They talk about fame, being chased, and the stars. She does a lively demonstration of the theory of relativity using the toys and flashlights and balloons. She tells The Professor he is at the top of her list of people she'd like to sleep with. They decide to go to bed, but are interrupted by the arrival of The Ballplayer, who has tracked her to the hotel. The Professor leaves them alone and goes to find another room, meeting a Cherokee elevator man with whom he speaks. The Actress and The Ballplayer talk about their marriage; The Actress tells her husband she believes she is pregnant, but he has fallen asleep. The following morning The Senator arrives at The Professor's room to find him gone, but The Actress naked and alone in The Professor's bed.
