WATCH: Woody Harrelson Discovers ‘Hunger Games: Mockingjay’ Cast Star Liam Hemsworth’s Brother Is People Magazine’s Sexiest Man Alive Amid Jennifer Lawrence Dating Rumors [VIDEO]

To many, it might seem obvious that Liam Hemsworth and Thor / People Magazine's Sexiest Man Alive, Chris Hemsworth, are brothers. To Woody Harrelson, not so much. In a recent sit-down for the new film Hunger Games: Mockingjay – Part 1, the former True Detective star had the sudden revelation when a journalist made small talk with Hemsworth about his brother before the interview. Harrelson was hilariously shocked, and couldn't get over the fact that he never put the two together. Little secret: we couldn't believe it either. Of course, despite being People's sexiest man alive, Chris isn't the one rumored to be dating Hunger Games star Jennifer Lawrence. That's right, Liam is!

"And Chris, how's he doing?" asked the journalist just before the junket. After Liam notes that he's busy playing the God of Thunder (Thor), Harrelson pats Hemsworth on the shoulder, saying, "I never guessed that was your brother!"

It seems that at first Hemsworth isn't sure whether or not Harrelson is joking. Truthfully, we weren't sure either, but watching further makes it seem as if he really had no idea. "...til just now. And you do have the same last name!"

The actor then added, "I honestly never put that together."

Check out this hilarious segment of Harrelson and Hemsworth's interview below:

Perhaps Harrelson is right. While The Hunger Games stars are getting a hefty amount of congratulations, maybe we should be acknowledging the brothers more, huh?

"Never even occurred to me," Harrelson noted, above a very humored Hemsworth and rather confused interviewer, who said, "They kind of look similar."

To that, Harrelson admitted, "Now that he mentions it, I totally get it."

In the end, is there really tea in that cup? Or is it scotch, as the former Cheers star jokes.
