This is the little guy on the Subaru commercials where the dad offers him the family car to drive. Super little actor. I hope we get to see a lot of him.
As for being blonde, my husband had (I say had because every single hair on his head is silvery white now) very dark black hair and mine is brown and both kids were blondes when they were little. One changed to be much darker and the other remained blonde. Probably a throw-back from the Scandinavian in me.
