The campaign, entitled "soundville", marks the first directorial work from Cabral since he returned to Argentina last year.
The ad, shot in Iceland in March, saw Fallon fill the town of Seydisfjordur with hundreds of speakers, turning the small hamlet into a soundstage.
Tracks by Mum, Bob Dylan and the Guillemots, among others, were then played while the reactions of the town's residents were captured on camera.
The spot carries the new brand strapline: "Make.believe."
The online film is being hosted on the Sony website, and although there are currently no plans to run the campaign on any other media channels, the possibility of TV coverage has not been ruled out.
