The Astrologer (1976)
This is an ego-trip on a Tommy Wiseau level. Craig Denney directed and starred in this, while the script is by a Dorothy June Pidgeon. Dorothy has this movie as her only credit, so I suspect this is actually Craig Denney's nom de plume.
It is a self-regarding tale of an astrologer who becomes so successful rich and famous, he decides to make a movie about himself. The editing's appalling, the acting worse. The plot includes pointless detours to Africa and the South Pacific, which add nothing very much to the whole sorry tale.
Fanboy Flicks just reviewed it on his YouTube channel. This one needs a solid riffing.
This movie is worth watching for the editing alone. I haven't seen whiplash-inducing jump cuts like this since Red Zone Cuba. And yeah, it's a delusional, self-grandizing, badly acted ego trip from the same planet as Wiseau and Breen. In other words, it's wonderful.
