Avatar is nominated for nine Oscars I believe...
Director: James Cameron
I don't think it deserves to sweep the Oscars, but my prediction is as follows:
Picture - WIN
Director: James Cameron - WIN
Editing - LOOSE
Cinematography - WIN
Art Direction - WIN
Visual Effects - WIN
Sound - WIN
Sound Editing -LOOSE
Original Score - LOOSE
So... I predict 6 out 9... so not a sweep, but a solid affirmation of what Cameron has achieved here.
Do I really think it should win some of these? No. For instance... best picture? Errr... no, but really now what else did we have this year that was any better?
I think Cameron absolutely deserves Director and the film deserves Cinematography and Visual effects. So if it were me I'd give 3 out of the 9 it was nominated for... but I think the momentum it has will garner additional awards.
