Quick summary here;
Lots of people, mostly under 25 from the looks of them, threw buckets of popcorn all over when the Chicken Jockey appeared. The movie was paused by the theater and identified offenders where escorted out.
Honestly people, just control yourselves. This is a kids movie, for crying out loud. It really screams "look at me, I'm a rebel and cool!" in only the most desperate way. I'm glad none of this happened at my local theater, we all just got to enjoy the film and share a laugh or two.
That was due in large part to the fully suited scenes being cut from the orginal show. The characters we know in the English version are really a separate cast.
