Diminuendo, the darkly-compelling sci-fi romance starring the late Richard Hatch in his final film performance, has made its official U.S. debut on Amazon Prime.

Diminuendo, helmed by first-time director Adrian Stewart, pairs Hatch with stars Chloe Dykstra (Drag Me To Hell , Truly Outrageous), Leah Cairns (Travelers, Interstellar), Gigi Edgley (Farscape) and Walter Koenig (Star Trek).

The Golden Globe-nominated actor, who gained worldwide fame as the star of the cult sci-fi television series Battlestar Galactica, had just completed filming the drama when he passed away in 2017.

Hatch plays Haskell Edwards, a has-been director whose life has crumbled in the decade since his Hollywood starlet girlfriend Cello Shea (Dykstra) committed suicide. When Edwards is offered the chance to direct the story of her life using a robot replica, he becomes tragically obsessed with Shea’s A.I. double.

Screenwriters Sarah Goldberger and Bryn Pryor created the role of Edwards specifically for Hatch, who was heavily involved in crafting the story and character. Director Stewart managed to finish a rough cut of the film for the actor to see before his death, and a memorial screening of that rough cut was held February 2017 in Hatch’s honor.

Distributed in the US by MyProduction and Lotus Entertainment, Diminuendo is available on Amazon Prime in the US and UK, with iTunes, FandangoNow and other VOD releases in the next few weeks, as well as a region-free DVD & Blu-ray release. Similar releases are set to follow in all other English and non-English speaking countries. View the official trailer on Vimeo.com.
