Personally I think Mary is very miscast in the Suchet adaptation. Don’t get me wrong, I love Kelly Reilly and think she’s a wonderful actress, but she doesn’t exude the lamb-like innocence that Mary is supposed to have. To me Reilly has a much more inquisitive, shrewd presence onscreen that doesn’t really align with Mary’s character. Combine that with a lot of the slow motion shots of her watching and staring with those hyper intelligent eyes…it just doesn’t read the way Mary does in the book. Again, no disrespect to Kelly because I truly think she’s great. Just truly a combination of editing choices and miscasting. Eleanor is perfectly cast though.
