One of the most legendary films coming from the Méxican
horror film wave. Well made by Chano Urueta
(the director of i.a. "El espejo de la bruja/The Witch's Mirror")
and with a cool Abel Salazar, the actor,
producer and director as the Baron and as the monster (he also acts
in "La maldicíon de la Llorona).
But even though this film has some amazing and almost art looking back-projections
this film is mainly
remembered for it's ridiculous looking monster, the brainsucking human
fly with it's forked rubber tongue
and hairy bulging head. The FX and make-up people must have had a fun
time coming up with this beast.
The film starts as "El espejo de la bruja"
did, with pictures by Francisco Goya and then the year is 1661
and the Baron Vitelius d' Estera (Abel Salazar)
is on trial by the Spanish Inquisition accused for being a
brujo, for using black magic and for seducing honorable women etc. etc.
The court founds that his crimes
were many and he were tortured and condemned to death by burning at
the stake.
But, as the code of horror films says he, before he dies, must be given
the opportunity of shouting out
a curse on his judges and their descendants: 300 years later, with the
return of a comet (seen in an awful
optical effect for once, they usually look fine in Urueta's films) he
will bring his revenge on them.

1961 Present Day: Three astronomers, a professor, Reinaldo
(Ruben Rojo) and his girlfriend Victoria (Rosa
Maria Gallardo) are looking for the comet. But it lands suddenly (now
turned into a meteor) and then
turned into the Brainiac, the fly monster, and then yet again turned
into human form, Baron Vitelius.
He kills a male car driver (audio commentary says this man is played
by the father of wrestling woman
goddess Lorena Velazquez) and takes his clothes, then neatly dressed
visits a bar where he kills the only
guest, a woman (Ariadna Welter). Then he starts his real work, the revenge
killings.
Why don't his victims try to flee from him ? The Baron
uses hypnotism on them and can materialize himself
wherever he wants, and he gets his strength from eating brain kept in
a cup in his bureau
