Sony Pictures Classics will handle the domestic theatrical release of sci-fi thriller “Moon.”

Pic, which has its first public screening at the Sundance Film Festival tonight, had been prebought last year by Sony Pictures Worldwide Acquisition Group.

“Moon” features the voice of Kevin Spacey and stars Sam Rockwell as an astronaut who is assigned to a three-year mission to mine energy source Helium 3 on the moon.

Pic is the feature directorial debut of British commercials helmer Duncan Jones. Script was penned Nathan Parker from a story by Jones. Jones’ partner at Liberty Films, Stuart Fenegan, as well as Xingu Films’ Trudie Styler produced. Music is by Clint Mansell (“Pi,” “”Requiem for a Dream”)

“I have always hoped for the opportunity to work with Sony Pictures Classics on the distribution of our film, even before arriving at Sundance,” Jones said in a statement. “Having their involvement is a huge point of pride for all of us and an incredible opportunity for ‘Moon.’ ”  

 SPC is set to release the film in June.
