VIDEO : What is Emma Watson's Fear? Wearing the Classic Yellow Dress in 'Beauty and the Beast'

Emma Watson was terrified of donning the iconic yellow dress in 'Beauty and the Beast'. The 26-year-old actress - who plays Belle opposite Dan Stevens as the Beast - admitted the most "nerve-wracking" scene for her in the live-action remake of the classic fairytale was when she had to perform the classic waltz with her hunky co-star because it is so "beloved" in the imagination of young girls and she didn't want to taint it for them.
