The writers are Levinson and Link, the men who created Columbo and Jessica Fletcher,
The lead actor is Robert Preston (The Music Man), starring as a writer who suspects that his wife's suicide was really murder. A year after her death, he has assembled the men and women of his wife's final performance in order to not only prove she was murdered, but also prove who did it.
This stars Lynn Redgrave (yes, one of those Redgraves), William Daniels (1776, Night Rider) as the producer, Patrick Macnee (Steed of The Avengers) as the last leading man she worked with, as well as a very, uh, uh, very, uh, young uhhhhhh, Jeff Goldblum.
This is one of the most brilliant pieces of writing you will ever see. And I know it's not Christmas-themed, but I'm not able to post Die Hard on the blog.
Also, if you haven't already, check out some of the books below. You might see some similarities in the writing. Heh heh heh.
