Audrey Hepburn excelled. The oscar was well deserved, and that too it being her first movie. Every scene kept me glued to the screen. There was so much happening: adventure, witty dialogues, aesthetic architecture and more.
That famous hair cut scene was icing to the cake. I rewatch it all the time. There's something about it, even though it's just a hair cut. Audrey's sheer glow and joy after seeing her hair chopped so short, the poise and the freedom she feels and exhibits, is too good.
