Any movie made after 1970 in the "scope" (anamorphic) aspect ratio is actually 2.39:1, not 2.35:1 - I believe the standard was changed to make splices less apparent. Because 2.35:1 was so ingrained in the minds of cinematographers and the like, it's still (usually) called that, even though it's really been 2.39:1 since 1970.
Some DVD cases now say 2.40:1 or 2.4:1, which is rounding up - the only DVD cover I know of that actually says 2.39:1 is Minority Report.
