I remember seeing Batman Begins on opening night, and a group of kids were on their phones being loud and attention-seeking in the back. Just your run of the mill juvenile shyt disturbers ruining the experience for everyone.
After some "shh"es from the audience, and a few polite "can you keep it down please?" comments, one of them was like "bytch shut the fukk up, we paid to be here just like you so if you have a problem, you leave". Well, that caused an eruption and I believe the son or husband of the woman that comment was directed at got up and threaten to "kick each and every one of your asses" lol!
For about 5 minutes there was yelling and some pushing/shoving and threats exchanged. The lights were still out and it wasn't clear what exactly was going on. Finally an usher came in and that group was escorted out. The entire theatre clapped and cheered, and the group yelled obscenities and ignorance on the way out, throwing their sodas and snacks into the audience.
They ended up rewinding the tape by like 10 minutes and getting through the movie with no distractions after. That was memorable
