The Exorcist (1973)
A fantastic Comedy/Horror movie that I cannot recommend enough is Sweeney Todd (2007). It has a lot of black humor, but is definately a horror movie and everyone I have spoken to about it agrees that it is a modern day masterpiece. If you would like more suggestions on horror or comedy movies, I suggest you check out imdb.com for suggestions. They even have lists about the most popular comedy and horror movies of all time.
According to the website movieweb, some of the most popular horror movies in 2007 are I Am Legend, Halloween, Saw IV, Grindhouse, and Hostel: Part II.
