LOS ANGELES - Clint Eastwood earned plenty of bad reviews for his latest performance: a bizarre, rambling endorsement of Mitt Romney.
"Clint, my hero, is coming across as sad and pathetic," tweeted film critic Roger Ebert as Eastwood ad-libbed Thursday night to an audience of millions - and one empty chair - on stage at the Republican National Convention in Tampa, Fla. "He didn't need to do this to himself. It's unworthy of him."
Eastwood carried on a kooky, long-winded conversation with an imaginary President Barack Obama, telling him that he failed to deliver on his promises, and it's time for Romney and his running mate, Paul Ryan, to take over.
Actor Clint Eastwood addresses the Republican National Convention in Tampa, Fla., on Thursday.
"Mr. President, how do you handle promises that you have made when you were running for election, and how do you handle them? I mean, what do you say to people?" he said at one point to the empty chair.
Twitter was instantly ablaze with comments mocking the Oscar-winning director of "Unforgiven" and "Million Dollar Baby."
"Clint has now eclipsed the total word count of his last three films," tweeted film critic Richard Roeper during the speech, which was intended to last five minutes but went on for nearly 12.
Howard Kurtz, host of CNN's "Reliable Sources," said "Clint's empty chair act" was the "weirdest convention moment I have ever seen." Joe Scarborough, the conservative host of MSNBC's "Morning Joe," declared that "a great night for Mitt Romney just got sidetracked by Clint Eastwood."
Minutes after Eastwood began his speech, someone created an @InvisibleObama account on Twitter. It has already amassed 30,000 followers and counting.
"I heard that Clint Eastwood was channeling me at the RNC," tweeted comic actor Bob Newhart, known for his one-sided conversation bits. "My lawyers and I are drafting our lawsuit."
The 82-year-old actor and director also talked about Oprah Winfrey, Obama's unfulfilled promise to close the U.S. prison at Guantanamo, the wars in Iraq and Afghanistan and lawyers. At one point, he referenced dismissing Obama and making a change.
"When somebody doesn't do the job, you gotta let 'em go," Eastwood said. The tough-guy actor of "Dirty Harry" fame then drew a finger across his throat.
