Stellan, crosses, shovel
Why make a prequel? To cash in on a film franchise, of course. But what happens when that franchise is over 30 years old, and child star Linda Blair has grown from a pea-soup spewing child into a career cameo? In the case of The Exorcist, you get not one, but two competing versions of the same film, with the same actors, the same shots, and completely opposing motives. Gus Van Sant replayed Psycho shot-by-shot, in homage to the original. In a weird twist, we've got Dominion: Prequel to the Exorcist, and The Exorcist: The Beginning, redundant homage unto themselves, which collectively go under the name Exorcist: The Prequel.
