Excellent Spanish Vampires' Parody! The idea of a Spanish 'guest worker' couple (Morales and Lopez Vasquez) being vampirized by their aristocratic German employers could have yielded an interesting horror-comedy, but in this film script and direction opt for a broad farce rather than corrosive satire.
The Spanish servants eventually escape Baron von Rosenthal and his bloodsucking family and return to their native country. On its release, the picture already looked about ten years out of date and in spite of the awkward references to Hammer movies, it seems to belong more to the 50's era of television sitcom, a format in which the popular Spanish comedy duo felt more at home. Lopez - Vasquez was one of Spain's most prolific comic actors. Lazaga was a veteran director of the many commercial Spanish cult-movies until the 70s.
