Help with the name of a movie

[Joeydl]

Ok i remember this from a long time ago , think its an 80's movie.

It was about some big guy (think he was big ) who could not be killed , he was buried alive in 1 scene .

Near the end the guy was in a toilet , i remenber he was leaning out of a window into the next room and someone then put a knife through his hand pinning it to the wall , he was then shot through the door .

This is really hard i bet but i have searched for years and can not find it , please help

This is a longshot guess...But could it possibly be "Humongous" early 80s film by Paul Lynch....Story about a deformed man-creature living in the woods and one by one kills the people that enter his lair.....
