After two films and several years of working together, for whatever reason, Woody Harrelson had never thought to put two and two together and conclude on his own that Liam and Chris Hemsworth were brothers. It’s not that he didn’t know who Chris Hemsworth was, or that he’d never heard of Thor, it’s just that the thought never occurred to him that he was working with the lesser Hemsworth (no offense) until a junket reporter brought up to Liam the fact that The Hunger Games was opening soon after his brother’s film, Thor: The Dark World.
The range of emotions that Harrelson goes through — from laid-back and totally high, to bemused and totally-high — are fabulous. He is clearly baked. Skip straight to the 3:50 mark.
