If anyone can make brandishing a rifle sexy…it’s Colin Farrell.

We spotted the Irish actor in Philadelphia on the set of his new flick Dead Man Down.  The 35-year-old looked pretty comfortable with the weapon in his hands…probably because of his role in 2003′s SWAT.

Farrell plays a New York mobster in the film who is grieving the loss of his family.

In other words…stay out of his way!
