@walesonline: Double Emmy nominee Matthew Rhys opens up to WalesOnline about the secret to keeping his feet firmly on the ground ahead of television's biggest night.📺 When asked if his success ever goes to his head, or if he thinks he's "chocolate", the Cardiff-born star attributes his humility to a distinctly Celtic state of mind. "It's a Celtic trait... almost an Olympic sport of waiting for someone to think they're too high for their station and to pull them down. The second you believe your own hype, it'll be the moment your entire social circle turns on you."
