The Exorcist (1973) often surfaces on AMC and other channels that have Halloween-theme movie marathons in October. It also appears on countless "Scariest Movies of All-Time" lists. Every time I watch it, I wish I would have been around to experience it with others when it was new. 
Today's horror movies are constantly trying to top each other in shock/horror value, but for a movie that came out in 1973, I think it still takes a lot to top Linda Blair's super-creepy possessed kid role in The Exorcist
2013 is the 40th anniversary of the 1973 classic The Exorcist.
