Toby Stephens' new movie The Machine was voted the best British film at the 2013 Raindance Film Festival.
The sci-fi thriller, which closed the festival on October 6, was picked ahead of three other rival films - drama Everyone's Going To Die, war movie The Patrol (which won film of the festival), and musical drama Titus.
Director Caradog James and producer John Giwa-Amu said in a joint statement: "We are incredibly honoured to win Best UK Feature at the 21st Raindance International Film Festival last night.
"To be nominated alongside such great films and talented filmmakers was amazing, but to win makes our UK premiere tonight the best launchpad for our UK release that we could hope for."
Toby plays an MOD scientist who creates an ultimate killing machine in the image of his lost love in The Machine, which also stars Caity Lotz, Denis Lawson, Sam Hazeldine and Pooneh Hajimohammadi.
Bosnian drama Halima's Path was picked as best international feature, while Italian drama The Art Of Happiness was voted best debut feature.
The winners of the 21st Raindance Film Festival, which ran from September 25 to October 6, were announced at the Vue Piccadilly cinema.
