Many years ago, one of my friends introduced me to Warren Murphy, author of "The Eiger Sanction." We all grew up in the same town in the Garden State, and spent one day enjoying some especially fine St. Pauli Girl brews at Warren's apartment, as I recall today.
I mentioned to Warren, that the apparent CIA honcho in the film was portrayed by the great Thayer David, Prof. T. Elliott Stokes of "Dark Shadows" fame. Warren said that he was aware of Mr. David's appearances on "Dark Shadows" and that he thought very highly of him as an actor. I could not agree more with Warren in his regard for Thayer David.
