Charles Dance
I may not be in favor of older men playing Frollo but I would say Charles Dance would make a Fantastic Frollo.

Charles Dance is most popular known for his role as Tywin Lannister in Game of Thrones
but the guy has a very impressive acting resume. I has also been in a Phantom of the Opera 
which I watch but I didn’t read. He also has a lot project come out including the third witcher game and Pride and Prejudice and Zombie.

But why would he make a good Frollo. Think Dance just excel at acting and his voice would just be awesome for Frollo. I think he would just knock Frollo’s complexity and torture out of the park. While Dance would be old for Frollo in the purest sense of the novel, he would fit the part in the austere harsh way. The harsh angular look is ideal for Frollo and so many times we don’t see those traits in the Frollo character.

If Charles Dance were to play Frollo I would be happy even if the purest part in my mind complain a little it would be quiet when Dance spoke his first line with an intense glare. What are your opinions on Charles Dance as Frollo
I haven’t seen any of the actor’s work, but just by seeing the pictures I think he would be good for the part! He has a really intense, blue eyes and for a character such as Claude Frollo, I think that should be more important than the age of the actor.
I think the role would sort of demand someone who isn’t a conventional young Hollywood actor…with the turmoil the character goes through, having someone who looks a bit more weathered would be a good thing.
