* CaliforniaDoubling: Set in Scotland, filmed in Luxembourg.
* DevelopmentHell: The sequel seems to be stuck here. It's been over a decade since the announcement of ''Dog Soldiers: Fresh Meat'', and though a trailer for ''Dog Soldiers: Red'' was revealed in 2011, very little is known about the status of the production.
* EnforcedMethodActing: Sean Pertwee was actually drunk for the scene where Cooper and Megan stitch up his wounds.
* FakeBrit: The British Captain Ryan is played by the Irish Liam Cunningham.
* NamesTheSame: Sgt. Harry G Wells is named after Creator/HGWells, one of Neil Marshall's favourite authors.
* ThrowItIn: During the scene where the delirious Sarge demands that Cooper knock him out, Kevin [[=McKidd=]] accidentally punched Sean Pertwee. The pause where [=McKidd=] checks on Pertwee after feeling the punch connect was left in the film.
** Creator/JasonStatham was originally cast as Cooper, but dropped out of the production to do ''Film/TheTransporter'' instead. In addition, a sequel was planned, ''Fresh Meat'', seeing Cooper encountering the American team his section was to have exercises with, as more werewolves emerge.
** Creator/SimonPegg was offered a role but turned it down to save his first horror film for ''Film/ShaunOfTheDead''.
** [[spoiler: Spoon's]] death was originally shown on screen, where he would be ripped in half by a wolf. It was given a GoryDiscretionShot because Neil Marshall didn't think audiences could handle such a graphic death for a beloved character.
