Johnny Depp in From HellFROM HELL

You can be forgiven for assuming that From Hell, Allen and Albert Hughes' re-telling of the Jack the Ripper saga (based on the immensely popular graphic novel), is a follow-up to Tim Burton's Sleepy Hollow, what with its previews focusing on a shadowy murderer, lots of fog and mist, Johnny Depp's investigator speaking in a British accent (Cockney this time), and Heather Graham in the Christina Ricci role of the Corseted Love Interest.

Jennifer Aniston and Mark Wahlberg in Rock StarROCK STAR and THE MUSKETEER

If you were to guess based solely on their previews, you'd probably imagine Stephen Herek's Rock Star to be a kitschy, affectionate look at heavy metal in the '80s - like This Is Spinal Tap played straight - and Peter Hyams' The Musketeer to be a brisk reinterpretation of the Alexandre Dumas classic with a martial-arts bent - Crouching Tiger, Hidden D'Artagnan.
