It's safe to say Chris Pine likes horsing around ... so excuse the salty bird.
Chris -- who plays Scottish King Robert the Bruce -- was on the set of his Netflix period drama "Outlaw King" and he gave the photogs an interesting welcome. Yup ... Chris was all smiles -- and pretty hairy, too -- as he flipped 'em all the bird.
In case you're wondering ... the earliest mention of the middle finger goes all the way back to 423 B.C. in a Greek play. You get a pass, Chris.
