I grew up in Louisville, KY where a promotional stunt was held for Demolition Man. A building was demolished, Sly Stallone and Dan Cortez pushed the button, MTV showed the building collapse live...it was a big deal.
That evening, there was a special advanced screening of DM. Unbeknownst to anyone, Stallone was scheduled to appear at the showing. When he arrived at the theater, people were cheering and chanting "Rocky" and "Rambo". Once the noise died down, my friend yelled "Stop or My Mom Will Shoot"!
Stallone whipped around and shot us an "Eat Shit and Die" look.
True story.
