For some reason, I can only imagine Lars Mikkelsen as Capricorn, even though he is a silly man in hindsight. But the Adderhead? Timothy Dalton. Timothy fucking Dalton, hell, I could hear his voice whenever the Adder spoke.
The Black Prince is such a great character, couldn't think of anyone other than Chadwick Boseman. RIP.

Mo's perspective in Inkspell (Tintenblut) was haunting, sometimes. The way his violent fantasies and wrathful thoughts feel so righteous, at first, and you think that he has every right to feel like this. Then you think back and realize that this is the man that refused to kill Basta in Inkheart when they had them by the shack in the woods, even though he'd threatened and hurt his daughter. And then it's clear that Mo is becoming something colder, harsher.
The cultural shock is interesting, though. I'm used to reading English books, usually by US or UK authors, and man are they much, much lighter than this.
The relationship between Mo, Resa, Dustfinger and Roxane is beautifully complex and nuanced.
IM SO CONFUSED,, WHY,, WHY IS THE INKHEART FANDOM SO OBSESSED WITH THE WORST MOST HORRIBLE CHARACTERS WHEN THERE ARE SO MANY WONDERFUL AND COMPLEX CHARACTERS AND STORYLINES AND CREATURES TO DRAW FROM WHAT THE- FIREFOX?? THE PIPER?? CAPRICORN?? B A S T A ?? W H A T WHAT WHAT
