Name That Trauma:: Rob B on Psychics & Seances

Hey, guys, this is my second post here. I received some help from the fan base about another movie I was trying to identify, and I was hoping you could help me with a couple of others, to wit:

1) I believe this first one was a made-for-TV movie from the 1970's. It begins with an old man (I believe it was Will Geer or a similar actor) out in the country, examining the ground closely as he walks along, eventually finding the spot he seems to be looking for; he buries a knife by the handle with the blade sticking up out of the ground, and walks off looking quite satisfied. I honestly can't remember anything else that happens until the moment of truth at the climax of the movie when a physical fight breaks out between two of the characters (m/m, m/f?) and the antagonist falls backward, right on the blade of the knife that was buried so cryptically at the beginning of the film which saves the day. Obviously some kind of psychic foreshadowing took place at the beginning, and I seem to remember the theme of more second sight related activity during the film but that's about it — the very beginning and the very end.

2) This was a British production, also from the 1970's (at least the video quality makes me think so) and involves a wealthy widow (I believe) who is trying to make contact with her deceased husband (or family member) on the other side. She has recently made the acquaintance of a somewhat younger man and they begin to develop a relationship as the age gap is not so pronounced. He accompanies her to one seance which involves people seated around a table, questions being written down, sealed into envelopes, and placed in a basket; the medium, a rather portly, middle-aged woman, opens the envelopes one by one and answers the questions, until the younger man jumps up, snatches the wig off of the medium's head ("she" is actually a female impersonator) and explains the con and how it works with the help of a confederate concealed among the "guests" (it's quite clever when it's explained, actually.) This cements the widow's feelings for this younger man (and his for her, ostensibly) as genuine, which, as we find out, they are not, as he is really an unscrupulous fortune-hunter solely after her money. At another seance at the climax of the movie, a Native American warrior appears and manages to kill this fortune-hunter by shooting him with several arrows that manifest themselves physically, thereby rescuing the widow from his dishonorable ambitions.

These titles of these two forays into the realm of the psychic and seances have eluded me for some time, and any help anyone could give me in identifying them would be greatly appreciated, Thank you, as always!
