Movie: The Shape of Things to Come (1979)
Legendary English author H.G. Wells was responsible for several sci-fi classics, most of which have been turned into memorable movies: The Island of Dr. Moreau, The Invisible Man, The Time Machine, War of the Worlds. Unfortunately, Wells' 1933 story The Shape of Things to Come didn't fare as well as those properties when director George McCowan took the title, kept a few characters' names, but then totally abandoned the book.
Actually, on second thought, Wells' work is better off not having any narrative connections here. The effects in The Shape of Things to Come are of the lowest budget, unable to match Wells' vivid imagination and never looking better than plastic toys being dangled in front of still-life paintings.
