A satire of 1950's from space-flicks and Black Sunday. Handles the story in a quasi-serious way, yet the absurdity of the creature/plot shows it's fun and campy, not meant to be scary. Urueta had a straight horror film that also homaged past films in The Witch's Mirror the same year, while Salazar's other mex-horrors are very gothic, so it's best taken as a repetitive and nonsensical, if misunderstood, satire.
An absolute must see. See it for the photo enlargements that stand in for locations. See it for the monster's bulbous pulsating head, the monster's inarticulate pincers and inarticulate tongue. See it for the bowl of brains. See it and know that a maniac with a lot of knowledge is a threat. Oh Brainiac! I’m with you in Aztlán and in my dreams you lurch across the soundstage to my door in the Western night...
In the history of bizarre ugly-ass movie monsters, the Baron Vistelius of Astara is certainly one of the most memorable. Sadly, his glory is marred by what turns out to be a rather repetitive movie. Full Review: http://cinephiledreams.blogspot.com/2014/01/the-brainiac-1962.html
Just to note: fellow monster kids brought up on '70s and '80s American late night TV will probably more readily recognize this by its more common TV title, THE BRAINIAC, which is usually how it was listed in TV guides back then. Truly terrible movie--but in a totally awesome way (like MANOS, etc). :D
