Colin Firth gets into a pub brawl in a clip from Kingsman: The Secret Service, Digital Spy reports.

The video sees Oscar winner Firth showing off his slick fighting skills against a group of local thugs in Matthew Vaughn's new spy movie.

The film centres around a troubled young man (Taron Egerton) who is inducted into a covert spy agency by his late father's colleague (Firth).

He begins training but soon finds himself pulled into a mission to save the world from a charismatic and maniacal industrialist (Samuel L Jackson).

Michael Caine, Mark Strong, Sofia Boutella, Sophie Cookson and Jack Davenport also feature in the movie.

Vaughn conceived the story with Mark Millar, who adapted the idea into a comic with Watchmen artist Dave Gibbons.

Kingsman: The Secret Service will be released on January 24 in the UK and February 13 in the US.
