Mind blown! Woody Harrelson was acting more like his drunken Hunger Games character Haymitch during one particular sit-down interview with his costar Liam Hemsworth back in 2013. While discussing their Lionsgate film Hunger Games: Catching Fire, Harrelson realized (for the first time ever!) that Liam's brother was none other than fellow Aussie hunk and Thor actor Chris Hemsworth.

"Jesus, I never got that he was your brother," the True Detective actor, 53, says in the 2013 clip, which resurfaced this week online. Hunched over with laughter, Hemsworth, 24, replied: "You didn't get that?"

"Until just now. And you do have the same last name, now that I think about it," Harrelson said, looking puzzled. "I honestly never put that together."

"Are you serious? You just got that now?" Hemsworth added. "You never cease to surprise me."
