Mysterious Movie Clips of the 1998 AMC Promo

In 1998, back when AMC had decent bumpers still, they did a bumper interspersing movie clips of people in theaters edited to be reacting to various iconic movies.

all the movie theater audience clips themselves come from various movies and someone on YouTube (the comment by "Phillip Zamora") has pinpointed almost all of them.

Except for two of them, and this is what I'm here to ask.

the two unknown clips:
0:24 - crowd applauds with black guy wearing fedora in front
0:36 - audience reacts in shot, edited to be as if they were reacting to Jurassic Park
