There’s no doubt that Joseph Baena is the son of Arnold Schwarzenegger. Even Arnold found out about it by only looking at the kid when he was seven or eight years old. He said that it wasn’t until "started looking like me, that's when I kind of got it. I put things together." Well, now Joseph is a copy of his father.
But if you look closely, you will see that he’s kind of a mix between Schwarzenegger and Warrick Davis who played the lead role in “Willow.”
