Al Pacino was treated by medics on the set of his new movie Stand Up Guys after hurting his eye in an explosive gun-wielding scene.

The Scarface legend has teamed up with fellow veteran star Christopher Walken for the movie, in which two ageing gangsters enjoy one last job.

The pair filmed a gunfight sequence on the streets of Los Angeles, with both firing off fake pistols in front of the cameras on Monday.

However, Pacino was left wincing in pain after the scene wrapped, and medics had to wash out his eye with solution.

It's not known how the actor was injured.
