Look, I know it's a pipe dream--that's what's so fun about it. If I could cast a movie version of Letters, these fine British, Irish and French actors would be my first choices:
Maisie Bristow: Felicity Jones

Adeline Westley: Andrea Riseborough

Stuart Hill: Matthew Goode

Peter Bristow: Jim Sturgess

Vaughn Rousseau: Gaspard Ulliel

Mr. Krause: Eddie Redmayne

James Murphy: Hugh Dancy

Julien Fortescue: Cyril Mourali

Brighid Murphy - Saoirse Ronan

Elyse Westley - Monica Bellucci

That is all for now--I am sure I will come up with more, and post them when I do. In the meantime, whom would YOU cast in these roles? Let us know!
