I stumbled upon a bunch of videos of a guy named Brian Hull doing incredible voice impressions of disney characters at disney parks. Watch a few:
Aside from the bang-on impressions, the bit I love most in these videos is when the person playing a character at the park—let’s be honest, probably an aspiring actor in their early 20s—reacts to the situation and what’s happening. You can tell Brian just made their day and for a moment they forgot about their long shift sweating inside a suit.
