Beginning with the death of Socrates in 399 BC, and following the story through the centuries to recent figures such as Bertrand Russell and Wittgenstein, Bryan Magee's conversations with fifteen contemporary writers and philosophers provide an accessible and exciting account of Western philosophy and its greatest thinkers.
The contributors include A.J. Ayer, Bernard Williams, Martha Nussbaum, Peter Singer, and John Searle, so that the documentary is not only an introduction to the philosophers of the past, but gives an invaluable insight into the view and personalities of some of the most influential philosophers of the twentieth century.
The series are little bit dated but I think they're real treasure and food for thought.
