A photo of Alfred Hitchcock with Barbara Harris, Bruce Dern, Karen Black, and Roy Thinnes on the set of Family Plot (1976).
Hitchcock had cast William Devane as Adamson, but by the time production got under way, Devane had to back out. Hitchcock recast with Roy Thinnes, only to learn that Devane was available again a few days into filming. Thinnes was removed from the role with no explanation, and Devane was back in.
There’s a famous story about Thinnes running into Hitchcock in a restaurant; Thinnes asked why he had been fired, and Hitchcock sat and said nothing until Thinnes finally gave up and walked away.
