An early attempt at comedy horror!  Although there isn't much comedy evident in the trailer.  Does the shocked photo of a sailor count?

Presumably the titular Undertaker tries to drum up business by sending out his "Pals" to murder people.  I can't imagine dipping people in acid and sticking corpses through a meat grinder did much to promote a positive image of his business, however.

In the unlikely event that you want to get hold of this film on DVD I strongly recommend you get it as part of the "Flesh Feast" set which features four movies and, bizarrely, sells for eight times less than The Undertaker... on it's own.

Favourite bit:  The voice-over from the "Producer".
