The actor is currently in the state to film new movie The Hit List with Christian Slater.
Video footage, obtained by TMZ.com, shows the star making a drunken speech at a local bar, winning over the crowd with his famous movie quote and a patriotic tribute to his native U.S.
He is seen grabbing a microphone and stepping up on a stage, telling bar-goers, "Show me the money. Show me the money!", a line from his 1996 film with Tom Cruise.
In a rambling speech, he added, "We are going to represent in the next five years, because you know what - we are the best country in the motherf**king world. And that's how we are going to do it. May those who love us all over the world, love us. May those who don't... may God bless their hearts. God bless the U.S.A."
