In Harry Potter and the Chamber of Secrets, the movie, the diary of Riddle pulls Harry in to view a memory. Riddle confronts Hagrid about Aragog and accuses him of causing the death of the student.
In the movie portrayal, however, Hagrid's face stays in shadow the entire time. Why is that? You still know it's him, due to his size and voice, and since Riddle outright says it.
Did the producers want to make the memory seem like a fake memory? According to the books, it was a real, unaltered, and unfabricated memory (from what I remember, at least).
Or perhaps they didn't want to find a similar actor? One that looked younger but whose face was still similar to Robbie Coltrane, for simply a 30-second clip of the movie.
As it was, it almost looks like they put in a different actor and used voiceover for the lines. It feels fake watching that scene, so I thought I'd ask to see if there was more of a reason for the portrayal shown in the movie.
