The first nomination was for Achievement in Art Direction, against 'Harry Potter and the Deathly Hallows Part 1', 'Inception', 'True Grit' and 'The King's Speech'. Alice in Wonderland was the winner of this category! Robert Stromberg (Production Design) and Karen O’Hara (Set Decoration) accepted the Oscar for Best Art Direction.
Carey Villegas was nominated for Best Achievement in Visual Effects for his work as visual effects supervisor on Tim Burton's Alice in Wonderland. The biggest competitor in this category was Inception.
“Inception” has some very good effects, Villegas said, but there were only 500-800 visual effects shots, as compared to 2,000 in “Alice.” The two movies both had won an award recently.
“Alice” had won the Golden Satellite Award for visual effects in December 2010 and “Inception” won the British Academy Awards in February 2011. So the competition was tight but in the end it was Inception that won the Oscar in Visual Effects category.
