Film Adaptations

I have been acting out some scenes from Masterminds, and I noticed something, I think. The majority of my favourite parts, the ones that shape my thoughts on the characters, are mainly narration and not dialogue. If you were to adapt your books to film, do you worry that you can’t convey the important things that make the characters who they are? 

I realised this after acting out Hector’s introduction chapter like 20 times.
