Another One Of Karloff's Odd Last Movies, 12 January 2007
Author: Bensch

"The Icredible Invasion" aka. "Alien Terror" of 1971 is one of the rather crappy and very odd last films of the great Boris Karloff. Released in 1971, two years after Karloff's death, this movie was directed by Jack Hill and Juan Ibanez, who also directed three other examples of Karloff's infamous last films, "Snake People", "The Fear Chamber" and "House Of Evil". While "The Incredible Invasion" is definitely a very crappy attempt of a Sci-Fi/Horror movie it is nevertheless very amusing and worth watching for its value as an unintentional comedy. While the movie does in no way rank behind "Snake People" in its oddity, it does not quite reach the unintentional fun-factor of "The Fear Chamber", as far as I am considered. Nevertheless it is great fun to watch and I could easily watch it again various times when I am bored and want to have a good laugh.

After Dr. John Mayer (Karloff) and his assistant Dr. Isabel Reed (Maura Monti) invent create a ray machine which produces some sort of nuclear power, a ray is accidentally shot into the universe where it hits a flying saucer. Reasoning that this sort of death-rays is too big a threat to the universe, the saucer's captain, a mysterious alien, who actually looks like a human being and wears a bizarre glittering seventies-style disco suit, decides to prevent earthlings from using it. The alien captain therefore lands on earth and possesses the brain of Thomas (Yerye Beirute), a serial killer of women, who operates as the alien's henchman from now on.

It would not be far-fetched to say that the Hill/Ibanez movies were to Karloff what Ed Wood's movies were to Bela Lugosi. Both brilliant actors and great stars of the horror genre, Lugosi and Karloff both ended their careers with some very odd films. Although they are without doubt unintentionally funny and they sure have some fans, however, the Hill/Ibanez films do in now way reach the cult status of Ed Wood's films.

"The Incredible Invasion" is terribly crappy as the Sci-Fi/Horror movie it tries to be, but it can be great fun if watched as the unintentional comedy it is. As far as I am concerned, every serious lover of film should watch at least one of Karloff's odd last films directed by Hill and Ibanez, just for the reason that they are some of Karloff's last films. Some other good reasons to watch "The Incredible Invasion" are lovely Christa Linder and Yerye Beirute, who also was in "The Fear Chamber". Don't expect any suspense whatsoever, but expect an unintentional comedy and laugh your ass off. 3/10
