"In Weird Al's movie UHF, the spoof of the Dire Straits "Money for Nothing" video was entirely produced on a single Amiga, where the original video required a high-end CGI mainframe. The Amiga was also used for the channel guide station by thousands of cable companies, and to show video bulletin board slides on public access channels."http://ozonegaming.org/amiga.php
'The "Weird Al" Yankovic film UHF contains a computer animated music video parody of the Dire Straits song "Money for Nothing", titled "Money For Nothing/Beverly Hillbillies". According to the DVD commentary track, this spoof was created on an Amiga home computer."https://en.wikipedia.org/wiki/Amiga
