Academy Award-winning director and actor Clint Eastwood was a surprise speaker at the Republican National Convention on Thursday, August 30.

The 82-year-old delivered an unconventional and, according to The Associated Press, unscripted speech that started with Eastwood standing on stage with an empty chair that he addressed as President Barack Obama.

Several times during the speech Eastwood would pause to address the invisible President Obama with a few questions and jokes aimed at the president's expense.

Obama himself responded to the Oscar winner's joke by posting on his Twitter page a photo of himself shown sitting at a chair that read "The President."

"This seat's taken," the U.S. leader wrote.

Immediately after Eastwood's speech a parody Twitter account called "Invisible Obama" began Tweeting about the convention and Eastwood. At press time the account had over 26,000 followers.

Eastwood also spoke of Obama's unfulfilled promise to close the U.S. prison at Guantanamo, the wars in Iraq and Afghanistan, the unemployment rate in the country and lawyers.

"When somebody doesn't do the job, you gotta let 'em go," Eastwood said.

At one point, Eastwood did a mock interview with President Obama directing questions to the chair such as, "Mr. President, how do you handle promises you made to when you were running for election? What do you say to people?"

Eastwood has a history of being involved in politics and was once elected mayor of Carmel, California in 1986. The actor and director endorsed Romney earlier this month at a campaign event in Sun Valley, Idaho.

Eastwood will return to the big screen in September as an actor in the film "Trouble with the Curve." He stars as an ailing baseball scout for the Atlanta Braves named Gus whose eyesight is getting worse. He takes his daughter, Mickey (Amy Adams), along for one last recruiting trip, as she promises to be helpful. Timberlake plays another baseball scout named Johnny who is a love interest for Adams.

The role is actually the first acting role for 82-year-old Eastwood in four years. He last acted in 2008's "Gran Torino," which he also directed. The film was directed by Robert Lorenz, who has produced several films with Eastwood.

"Trouble with the Curve" hits theaters on September 28.
