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.
