I don't remember the movie name but the credits might help, corpse was one of the chipowski brothers. Maybe the first picture's from a different movie.
I feel like I should speak up, since I said the title first. It was most certainly head above water and you proved it with this review. Billy Zane is dead in bed in the pics and he is dead in bed in the review and dragged to the cellar as in the pics.
I first rented this video with hopes of catching a shot of Craig Sheffer's feet, I had given up on billy Zane at the time. I was completely in shock when they showed and focused on Zane's feet and him only in his underwear. Truly, The best of all times. Sheffer didn't show anything in this movie, but I was far from disappointed.
