While Falling Skies may only be a few episodes into its first season, Noah Wyle has been nominated for a Teen Choice award. The category he's nominated for is "Choice Summer TV Star: Male" which includes Keegan Allen, Lucal Grabeel, Ian Harding, and Tyler Posey.
Because the award is based on the votes of teenagers, my guess is that Noah Wyle doesn't stand a chance. This is also likely why Falling Skies isn't up for "Choice Summer TV Show" when shows like "Keeping Up with the Kardashians", "Switched at Birth", and "Pretty Little Liars" are.
Either way, it's great to see Noah Wyle get some recognition, even if it is for the Teen Choice awards. Let's hope he can pull off an upset!
