If he thought somehow the blue-eyed look would create a better resemblance of Sinatra, he’s wrong, but with that facial shape and structure, Ronan certainly looks like he could be Sinatra’s son.
Look at Sinatra’s other kids. Chairboy looks like a debauched version of his old man and while Nancy looks like him, she bears no relationship to the appearance of Ronan Farrow. The Sinatra features are coarsened in the children.
Perhaps the kid is neither Sinatra’s or Allen’s. Anybody think about that?
