This is the moment Woody Harrelson realised his co-star has a very famous brother

Liam and Chris Hemsworth are among Hollywood’s most well-known siblings - but Liam’s long-term co-star in the Hunger Games, Woody Harrelson, never made the connection. Until now.

In this recently rediscovered video the pair were being interviewed about the then upcoming Hunger Games: Catching Fire and Liam made small talk with the interviewer, noting that he shared a first name with his brother Chris.

If you watch Woody very carefully you'll see the exact moment the penny drops.
