I'd like to give a little visibility to this movie here: "Pirata! a cult movie" from 1984, but filmed between oct. '82 - feb '83, by 25 year old director Paolo Ciaffi Ricagno and presented to the Venice international film festival of that year.
Pirata! a cult movie
The plot goes something in the lines of: In a hypothetical future, the Supreme Dreamer models people's behavior through the "Hat of Dreams" network. His dominion is threatened by a rebel businessman, the Pirate, who carries out an attack on the network's transmission center, overthrows the Supreme Dreamer and replaces him, however imposing a dictatorship similar to that of his predecessor.
Whatever; but it really stands out videogaming wise for two reasons, in my opinion:
1) inserts of video game snippets into real life footage (i.e. see min. 12.55 - but few more along the way - and I think this is pretty unique);
2): an entire sequence filmed in a '80s italian arcade (from min. 22.00 on).
So take some popcorn and a beer and give it a try!
Cheers!
