Apple has posted on its Web site a QuickTime version of its "Leathal Weapon G4" TV ad for the new Power Mac G4.

The ad portrays the G4 surrounded by army tanks, with the music from "the Great Escape" in the background.

The inspiration came when the machine’s "supercomputer" epithet caught the attention of the Pentagon, which regards supercomputers as "strategic technology" – a weapon that shouldn’t fall into the wrong hands.

According to reports, the US government has banned Apple from shipping the G4 supercomputer to certain politically volatile countries.

QuickTime 4 is required to view the ad, which will be aired on US TV from August 31 until September 19.
