General Hummel

"You alert the media, I launch the gas. You refuse payment, I launch the gas. You've got forty hours, until noon, day after tomorrow, to arrange transfer of the money. I am aware of your countermeasure. You know and I know it doesn't stand a chance. Hummel from Alcatraz, out."

- General Francis Xavier Hummel's instructions to the FBI before disconnecting.

General Francis Xavier Hummel, also known as Gen. Francis X. Hummel and "Frank", is the main antagonist of the movie The Rock. He is an USMC Force Recon Brigadier General, and a rogue military commander who, disgusted with the U.S. military's lack of regard for America's fallen soldiers, steals 15 VX poison-equipped guided rockets to hold the city of San Francisco hostage unless the payment he demands for the soldiers' families are met.

He was portrayed by Ed Harris who later played Mitch Wilkinson in National Treasure: Book of Secrets.

Before the movie began, he served with the U.S. Marine Corps, even in the Vietnam War. At the time the movie starts, Hummel and his gang of Marine Force Reconnaissance operators steal 15 VX posion Gas rockets at the expense of one of his men. On a tour of Alcatraz, Hummel captures the tourists and the tour guide. He then demanded that money be transferred to the families of the Marines who lost their lives for his cause.

Upon hearing that a SEAL Team with Stanley Goodspeed and John Patrick Mason involved, his men kill them all (except for the 2 protagonists) despite orders not to shoot. When things get out of hand, he threatens that Stanley return the guidance chips or he will kill a hostage. Goodspeed and Mason are both captured.

When a VX missile fires the next day, Hummel changes the coordinates and sends it to the sea instead. His men argue with him over what went wrong. Hummel ordered his men to pull out with the VX in the choppers and 4 hostages as well. With the bluff called, his men (other than Maj. Baxter who has been Hummel's bodyguard) betray him and want to go ahead with the missile launchings.

Hummel and Baxter manage to shoot some of the betrayers before Hummel himself is shot. Goodspeed pulls him to safety and the dying general with his last breath tells Goodspeed to go to the lower lighthouse for the last VX rocket.
