Benedict Cumberbatch has enjoyed a meteoric rise in recent years, becoming known the world over for his roles in The BBC’s Sherlock, Tinker Tailor Soldier Spy, and most recently Star Trek Into Darkness. But that doesn’t mean the actor only seeks out blockbusters to show off his skills.

That’s clearly evident with his next appearance in the small-scale, indie short film Little Favour. Moviegoers who have yet to see Cumberbatch give up the role of ‘mastermind’ and take a beating onscreen may want to keep an eye out for this one, as the first trailer shows that a “little favour” can have serious consequences.

The film follows Cumberbatch’s character ‘Wallace,’ a former British secret service agent whose life was saved by an American agent in Iraq. Ten years later, that American agent (played by Colin Salmon) returns to cash in the debt, asking for Wallace’s help with a “little favour.”

The first teaser trailer for the film hinted that the favor in question wouldn’t be so simple after all, and the full-length trailer proves it: Wallace’s life is put on the line, leading to some quick thinking (and plenty of violence) if he hopes to make it out alive. Those who saw Tinker Tailor Soldier Spy know that Cumberbatch is right at home in the cloak-and-dagger world of secret intelligence, so Little Favour is off on the right foot – albeit with a much bloodier updating.

The short film was written and directed by Patrick Viktor Monroe, bringing serious talent with him despite his ‘newcomer’ status. The project was crowd-funded through a wildly successful Indiegogo campaign, with Screen Rant founder Vic Holtreman’s donation earning him a credit as executive producer!

A gritty, bloody crime thriller is always welcome in our books, and with the likes of Cumberbatch, Salmon, and Nick Moran (who Harry Potter fans will recognize from the final two films), we’re eager to see the outcome. What do you think of the trailer?

Little Favour will be available through iTunes on November 5, 2013.
