Richard Armitage
As a possible movie (or mini-series) Frollo I would suggest Richard Armitage for the role. While Armiatge is younger and more attractive than Frollo is meant to be, he has a talent for playing brooding and complex characters.

Armitage’s biggest roles have been playing John Thornton in the 2004 BBC version of North & South
Richard Armitage as Guy of Gisborne from the BBC version of Robin Hood
Armitage is a very versatile actor. I think he pull off the descent into insanity very effectively. I know Armitage could give Frollo the complexity he has in the book but is lacking from other film versions.

As for his looks, yeah Armitage would be a handsomer and younger Frollo but his looks work with the character. He is tall and lean which would enhance Frollo’s austere look. With the right costume and make-up he could be made up to look like the ideal Frollo.

Tell me what do you think. Do you like Richard Armitage would make a good Frollo or do someone else is the perfect Frollo?
Bonus – Armitage was also in Captain America as Heinz Kruger and in Star Wars Episode I The Phantom Menace as Naboo Fighter Pilot (he was uncredited)
