LOL!
I just read another interview with Hanno (through google translate); I didn't know he also has a daughter. There's really no info in the US press about either of these guys. Usually when you google an actor or actress, you get pics of their girlfriends/boyfriends or husbands/wives, who they're dating, etc. But seems like the German press is not covering that at all. Which is good for Hanno and Max, keeps their private lives private.
As far as I know (from interviews and other stuff I found on internet), Max doesn't want his private life in the spotlights. I heard a German radio interview (a recent one) and the interviewer said: when we heard you were coming, everyone said: wow, he's good....but he's also introverted.
After hearing the interview, I thought: no, you are not introverted at all. Just not a guy who only wants to talk about superficial (or triviant, don't know the right word) things and in fact he showed a lot of himself. My opinion: beautiful outside and inside.
I also read a review from someone who saw the free fall premiere in Berlin. After the movie, director and cast came on stage.
The review said: Hanno was very confident, Max seemed shy and left the stage as soon as he could.
And in another interview Max said: I don't want my friends and family to read nonsens about me in gossip magazines.
So all together I think Max protects his private life.
I'm talking too much about Max again

And I didn't know Hanno had a daughter.
