I bring this up every year for Halloween. Martin Peyton actor George Macready has a wonderful part in his Son's movie Count Yorga Vampire. George speaks at the start of the film about what a Vampire is. The words that he speaks are wonderful. TCM does play the movie if you can catch it.
The other Martin Peyton visits the grave of his daughter Catherine. The one is filmed in 1966 in a very beautiful way. Fall leaves and the camera work is great. The dialog between Martin and Dr Rossi wonderful. The other is in 1967 same time of year and again camera work and the dialog in that scene are beautiful. Voyage fans can see the grave stone of Lani from the Phantom Returns while Martin is speaking in the 1967 episode.
