The latest INDY CAST Indiana Jones podcast (episode 266) features an interview with author Mark O'Connell about his book, WATCHING SKIES -- a valentine to films and pop culture of the 1970s and 80s, particularly Spielberg and Lucas lore.
I've yet to pick up O'Connell's book, but eagerly look forward to reading it. In the podcast, O'Connell mentions his particular fondness for Richard Amsel's poster art, and the sense of magic they inspired.
