N is a Number: A Portrait of Paul Erdös (Springer VideoMATH)

"This documentary film is an inspiration and a delight. [...] In summary, this film is a wonderful eulogy to this gifted and amazing man. It will encourage, inspire and enthuse all who have an interest in mathematics, and fascinate those who have not. It is a great resource, and should be required viewing for all university mathematics staff and students."

Paul Scott, gazette, The Australian Mathematical Society, Volume 33, Number 1, 2006
