His characters never have children

I was watching Knock Knock and the beginning has scenes of him being a playful father to his two kids...and it's pretty damn awkward. It occurred to me that I don't think i've ever seen him play a character where he has children. He's almost always a loner like in Speed, The Matrix, Constantine, A Scanner Darkly, etc. And when he plays a character that has a wife, they don't have kids, like in The Devil's Advocate. Heck, in John Wick, he's getting revenge for the bad guys killing his dog!

I have to wonder if it's Keanu's request to not have to have kids in his films or if studios just don't see him as the father type. It's like he's the opposite of Harrison Ford, who is always trying to save his family. Or Arnold Schwarzenegger who will murder hundreds of people to save his kidnapped daughter like in Commando or True Lies.

I wonder how Eli Roth got Keanu to play a daddy after all these years.

(granted, i've not seen every Keanu movie, so I could be missing some examples)
