"Hummel from Alcatraz, out."
One of the things that separates The Rock from more basic Bay fare is the mashing of action styles. There is the buddy-action-comedy element with Cage and Connery, but it’s also a hostage movie, pitting General Frank against the White House -- and for that, a Situation Room-esque location is introduced.
The original point of this entire scene is to establish three things:
1. General Frank’s very impressive bio, which includes three Purple Hearts, two Silver Stars, several Yellow Moons, Green Clovers, and Red Balloons, plus a Congressional Medal of Honor.
2. Reconfirming that Hummel is not a villain. The movie strives to let you know that this man is not what he seems. When the White House Chief of Staff calls him a hero, he’s corrected. Hummel is A LEGEND. Even when he’s demanding $100 million ($83 million of which is going to families of dead soldiers!), he doesn’t want to take taxpayer money for it. Instead, he asks that it come from the Grand Cayman Red Sea Trading Company, which is a slush fund where the “Pentagon keeps proceeds from illegal arms deals.” Hummel is basically running for office while he’s holding hostages.
