Scream 2. Went to see it at this independent local multiplex where they always used to do cool stuff.
So the movie opens with the part where they're in a theater Omar and Jada get that work and Jada runs down to the front of the theater and screams and dies just a few minutes in. Right as she's dying a Dude in the full Scream Robe/Mask come running out from down behind the screen w a Knife up the aisle and all hell broke loose. Folks jumped up in their seats, women screamed, niccas broke for the exit.
Panther - they took a couple hundred of us to go see this back in highschool at a theater out in the burbs. After it was over we were all out front holding a mini rally and yelling stuff from the movie at white people coming in to see matinees. I remember specifically a chant of "fcuk Ronald Reagan" and seeing people turn around and walk back to their cars lol.
Blair witch project, pre-hype. At an arthouse theater on the northside. Strictly word of mouth, people were still thinking it was real. Made it extra creepy.
