Casting

Oh I just discovered this movie. When I saw the BBC documentary "A dark and stormy night" I immediatly thought this would also have been good as a movie. And I made a casting list for that.

Hope this will be like that. I wonder if Lord Byron is in it and who plays him. I had suggested Aaron Taylor-Johnson. And I wonder about casting choices. Bel looks fine as Claire, but Ellen doesn't look like Mary at all, but I love Ellen and I am sure she will be a great Mary. As Percy I suggested Luke Newberry. But Douglas Booth is also a good actor. And Plidori? His character must be in this, too. I suggest Aneurin Barnard. I know there is make-up and acting is more important than looking exactly like the original persons, so I hope this will be a good movie. It seems to focus only on Mary and Percy. I hope the others will be in it too. This documentary was really great.
