This is also when the filmic allusions start piling up into their own sort of zombie brigade: scare quotes, if you like, from Don't Look Now, Carrie, Apocalypse Now, The Blair Witch Project, the Gollum sequences in The Lord of the Rings, The Texas Chainsaw Massacre, the original Alien, and in one sudden flash-reveal of a whole brigade of crouching monsters, a direct lift from Aliens.
For more recent echoings, go to The Time Machine , Alien , First Blood, The Blair Witch Project , Pitch Black and Buffy the Vampire Slayer, for starters.
They include explicit allusions (in addition to the movies already mentioned above) to " Picnic at Hanging Rock ," " Carrie ," “ 2001: A Space Odyssey ,” " The Third Man ," "The Fourth Man," " Don't Look Now ," " The Blair Witch Project " " Vertigo ," " Apocalypse Now "... and plenty more.
The shocks occasionally stray into the derivative -- elements of The Blair Witch Project hang uncomfortably in the air, and a few clichés mar the proceedings every now and then -- but they never run out of steam, and you rarely see them coming before they hit you full in the face.
Only two films in the past few years accomplished this feat: The Blair Witch Project and Gore Verbinski's remake of the Japanese horror film, The Ring.
Marshall is also an astute 'borrower' of other films, from the piton clipping suspense of "Cliffhanger," to the video camera revelations of "The Blair Witch Project" to a combined "Carrie"/"Apocalypse Now" moment that wows with its audacity.
