Telescope A Talk With Alfred Hitchcock.
This two part Canadian TV show interview from the sixties with Hitchcock has a number of interesting revelations which aren't commonly seen in available interviews. It also has some side interviews that are really fascinating. One is Bernard Hermann talking about how the two work together. There are also two important producers and friends of Hitch's; actor, producer, director Norman LLoyd and Joan Harrison. Harrison started as a secretary in England with Hitchcock, moved up to producer and has writing credits for Saboteur, Suspicion, Foreign, Correspondent, Rebecca and Jamaica Inn. She also worked on over 200 of his TV shows.
On Hulu streaming. Essential for any film buff.
Note at the beginning of December a documentary about the book Hitchcock/Truffaut is being released. If you only have one book about film making this is the one.
