N Is a Number: A Portrait of Paul Erdős is a 1993 documentary directed by George Paul Csicsery about the life of mathematician Paul Erdős.
Erdős himself appears in the film. As of 2007, using the official cast list in the credits, it gives Erdős a Bacon number (and thus Erdős-Bacon number) of 4. However, Sir Alec Guinness, identified by name by the narrator, appears in the film, getting an honorary doctorate with Erdős; his presence would give Erdős a Bacon number of 3. Since Frost/Nixon was released in late 2008, Erdős has a Bacon number of 3 through official credits.

In April 2013, a lecturer at the University of New Hampshire submitted a paper to the Annals of Mathematics. Within weeks word spread: a little-known mathematician, with no permanent job and working in complete isolation, had made an important breakthrough towards solving the Twin Prime Conjecture. Yitang Zhang's techniques for bounding the gaps between primes soon led to rapid incremental progress by the Polymath Group, and then to a further major innovation by James Maynard. The film is a study of Zhang's rise from obscurity and a disadvantaged youth to mathematical celebrity. The story of quiet perseverance amidst adversity, and Zhang's preference for thinking and working in solitude, is interwoven with a history of the Twin Prime Conjecture as told by several mathematicians, many of whom have wrestled with this enormously challenging problem in Number Theory-Daniel Goldston, Kannan Soundararajan, Andrew Granville, Peter Sarnak, Enrico Bombieri, James Maynard, Nicholas Katz, David Eisenbud, Ken Ribet, and Terry Tao.

A one-hour biographical documentary, Julia Robinson and Hilbert's Tenth Problem tells the story of an important American mathematician against a background of mathematical ideas.
Julia Robinson (1919 – 1985), a pioneer among American women in mathematics, rose to prominence in a field where often she was the only woman. She was the first woman elected to the mathematical section of the National Academy of Sciences, and the first woman to become president of the American Mathematical Society.
Her work, and the exciting story of the path that led to the solution of Hilbert's tenth problem in 1970, produced an unusual friendship between Russian and American colleagues at the height of the cold war. In this film, Robinson's major contribution to the solution of H10 triggers a tour of 20th century mathematics that moves from Paris in 1900, through the United States, to the Soviet Union and back.
Following the passionate pursuit of an unsolved problem by several individuals in different countries adds to the emotional intensity of the mathematical quest.
This film covers important events in the history of modern mathematics while conveying the motivations of mathematicians, and exploring the relationship between mathematical research and the development of computers. The key protagonists and advisors to the project are recognized as the most prominent in their fields.
Julia Robinson's story, and the presence of prominent women in mathematics in the film, should inspire young women to pursue educational opportunities and careers in mathematics.

Hard Problems is about the extraordinary gifted students who represented the United States in 2006 at the world s toughest math competition: The International Mathematical Olympiad (IMO). It is the story of six American high school students who competed with 500 others from 90 countries in Ljublijana, Slovenia. The film shows the dedication and perseverance of these remarkably talented students, the rigorous preparation they undertake, and the joy they get out of solving challenging math problems. It captures the spirit that infuses the mathematical quest at the highest level.
