Finnick Odair (Sam Claflin) enjoyed a moment of happiness when he was reunited with his lady love Annie at the end of "The Hunger Games: Mockingjay -- Part 1." But it sounds like his happiness might be short-lived when "Mockingjay -- Part 2" storms into theaters this November.

On the most recent episode of Josh Horowitz’s Happy Sad Confused podcast, Claflin revealed that he had his "worst day of filming" ever while shooting the conclusion to the popular "Hunger Games" franchise. "I think I actually got hooked up to oxygen tanks," Claflin said. Yikes!

While Claflin didn't want to spoil that scene too much for moviegoers, he did give us one tiny tease for what's to come. "I'd like to think the conclusion to this franchise won't disappoint people," he said. "It's bigger! I'm very excited."

Of course, he also briefly opened up about his character Finnick's fate, and as a warning to non-book readers, there are some serious spoilers approximately 34 minutes in.
