I can remember back in the early 1990's bootleg VHS copies of this going around, that was the only way you could see this here in the UK. I didn't bother but 30 years later I have just watched the official Blu-ray release, it was kinda worth the wait. Sold as a slasher but there is no slashing, Luther uses his metal teeth to not only rip the heads off chickens but also to make a very bloody mess of peoples' necks! He also drinks blood so arguably he is part crazed vampire but without any supernatural elements. The timeline is all wrong, we first see Luther as a young boy in 1938. He is convicted of several murders in his late teens and serves 20 something years in jail before being released. I would date that sometime during the 1970's but this is clearly set/filmed in the late 1980's! Most of the film has Luther holding a woman, her sexy daughter and her lucky boyfriend hostage in their farmhouse, so it is in part a home invasion movie. Although the acting is rather amateur Edward Terry puts in a memorable performance as the horrible. Freakish Geek. I often side with the bad guy in slasher movies, for example Jason in the Friday the 13th's, but Luther is truly vile and I wanted him to suffer. Sadly his victims make so many dumb decisions that I found it hard to side with them either. Stacy Haiduk gets naked for some almost soft pornographic sex scenes and she looks amazing. Despite its failings Luther the Geek packs in some serious gore and should appeal to most splatter movie fans.
