While probably not an Oscar-worthy performance in and of itself, I think many people who enjoyed the movie of Lord of the Rings: The Two Towers believed Andy Serkis's performance as Gollum and the animation and technical work that completed the character were something special. I wondered if the Academy might have considered Gollum a special achievement of some kind, or if the Academy even did such things.
It turns out they do. In fact, Who Framed Roger Rabbit received the Special Achievement Oscar for their work in combining animation and live action. I wonder what other recipients of the Special Achievement there have been?
WikiPedia has recipient lists by category, which is nice, but their Special Achievement page is blank! I'll have to add Roger Rabbit. Are there others? Too busy to research this further, alas. :)
In case you haven't seen the bazillion TV ads for it, there's a new Who Framed Roger Rabbit DVD with a new restoration, a big ol' commentary track, and a bunch of the usual extras. Two discs, "one family friendly, one for the enthusiast," a weird-ass way of implying kids don't like widescreen features but do like animated kiosk menu "games". Thanks Mermaniac for mentioning the DVDFile in-depth review.
