Katheryn Winnick and Charlie Sheen Croon Through 'Aguas de Marco' - Song Premiere

In Roman Coppola's new film A Glimpse Inside the Mind of Charles Swan III, Charlie Sheen stars as a graphic designer who's quite good with the ladies yet gets dumped by his girlfriend (Katheryn Winnick). As he sorts out his thoughts, he struggles with nightmares of his past relationships and is forced to reassess his life. Coppola enlisted Liam Hayes, better known as Plush, for the film's soundtrack; here, Hayes brings Sheen and Winnick together for a Portuguese duet on Antonio Carlos Jobim's "Águas de Março." Winnick seductively curls her syllables around the swooning strings and breezy percussion, and Sheen chimes in with a unflappable confidence and surprising dexterity.

"Maybe it's a rainy day in the song, but what a wonderful song to sing," Hayes tells Rolling Stone. "Charlie's rendition is playful and it's also sincere." A Glimpse Inside the Mind of Charles Swan III opens to a limited U.S. release on February 8th. The soundtrack is due February 5th.
