Kingsman The Secret ServiceWhen Colin Firth is having an "emotional day," you do NOT want to mess with Colin Firth.

That's the harsh lesson he doles out to a group of thugs in this new action-packed trailer for "Kingsman: The Secret Service." This footage proves that Firth isn't just a eloquent, debonair mentor to Taron Egerton's street punk - he can kick ass and take names as well as any spy.

"Manners maketh man," Firth sniffs, before dispatching the thugs.

The new trailer also features quite a bit of Samuel L. Jackson being hilarious; Michael Caine being, well, Michael Caine-like; and a lot the stylish action set pieces that are the hallmark of director Matthew Vaughn. Oh, and it's all accompanied by a thumping new song from Iggy Azalea and Ellie Goulding.

"Kingsman" opens in theaters Feb. 13, 2015.
