The marvellous bare.bones website has published another of Jack Seabrook's insightful reviews of The Alfred Hitchcock Hour. This latest instalment is a detailed breakdown of the episode "The Life Word of Juan Diaz", which was scripted by Bradbury and based on his own short story. You can read Jack's review here. (My own review of the same episode is on my Alfred Hitchcock Hour page, here.)
Jack's other reviews of Bradbury/Hitchcock episodes are all worth reading. There are collected here.
