I'm looking for a horror movie?

First off all- sorry for my english ;)

The movie tells the story about a magician (he looks ugly, he is fat
and old, his skin is full of acne and other shit); he is a bad person-
black magic magician. He got few students and one of him wants to kill
him, by burry him allive. After a few years the magician comes to
allive again. The story of this movie is on the desert. Charakteristic
thing of this movie is that magician levitate a lot. When student
burry him alive he also sew his mount.
Thx a lot for helping me!
