Help? Please?
Argh and dammit. I remembered this recently, and I've been searching for this for weeks, and it's been driving me up the damn wall.

Roughly seven years ago, one summer, I stayed up way too late and saw this... thing on some movie channel. I don't even know if it was a full length movie or an episode of something, but I'm hoping y'all can help me.

This artist guy, played by David Bowie, has these creepy Hirst-like installation pieces involving what looks like pieces of lifelike dolls frozen in blocks of ice. He hires himself an assistant, who takes the opportunity to start learning about this kinda stuff, but gets in over his head and discovers this is a Vincent-Price-House-of-Wax scenario, where Bowie's character is actually killing and dismembering people for his pieces. Bowie's character finds out his assistant's been snooping, we go into a "you know too much, so I have to kill you" deal, and there's a big fight. Then, at the very end...I think even after the credits have rolled, I could be wrong, we see Bowie's character all hacked up in ice, ready to be put in a gallery.

Ring a bell to anyone?
