Actor-director Clint Eastwood has reiterated his support for gay marriage.

The 82-year-old Eastwood appeared Monday on the Ellen DeGeneres Show to pitch his new movie, Trouble at the Curve, which opens nationwide on Friday.

Eastwood's appearance at the Republican National Convention (RNC) raised eyebrows when he conversed with an invisible President Barack Obama who was supposedly seated in an empty chair.

“The Democrats who were watching thought I was going senile, and the Republicans knew I was,” he joked.

Eastwood explained that he leans more Libertarian, and knocked the GOP for abandoning such values.

“Libertarian values, that's where Republicans used to be when they were saving money and everything,” Eastwood said.

On gay marriage, he said: “Leave everybody alone. … With the condition of society right now, with the high unemployment rates and the tremendous debt we're increasing and the government spending, you think there'd be a lot to think about … [instead of] worrying what gay marriage is about.” (The video is embedded on this page.
