Josh Brolin appeared on "The Tonight Show with Jay Leno" to talk about preparing for and promoting his new movie, "Men In Black III."

Throughout the promotional tour, Brolin recalls that he was a "Goonie" first and foremost to fans across the globe. He just can't seem to move past his break-out role, and Jay doesn't help by playing a clip from the beloved classic. He has moved on to new projects though, most recently taking on the role of the young Tommy Lee Jones -- or should we say, "Agent Kay."

Check out the video above where Brolin discusses the challenges of imitating Jones' unique cadences, plus a clip of him in action in the new movie.
