Presented as a series of vignettes, 'Bygone Behemoth' follows the title character as he putters around his house, laments being out-of-shape, calls his agent about work, reads the want-ads, and contemplates the obituaries. No longer gracing the silver screen, his memories are now banished to late-night syndication on a 'Chiller Theater' type program featuring 93-year-old WPIX horror icon John Zacherley, a live-action reflection of the Behemoth himself.
