The F-16 stolen by Michael Douglas and Kathleen Turner was actually a full-scale mock-up powered by a 350ci Chevrolet engine, if you look closely you can see the driveshafts running from the belly of the plane to the wheels on the landing gear.
The end title song is Billy Ocean's "When the Going Gets Tough, the Tough Get Going". In the music video for the song, stars Michael Douglas, Kathleen Turner and Danny DeVito lipsync and dance as doo-wop backup singers. Because the three stars were not members of the Musicians Union, the video was banned in the UK. Despite this handicap, the song would be Ocean's first #1 UK hit.
