Findlay is fairly new to Hollywood as her top credits are Downton Abbey and Winter's Tale. She also had a small role in Black Mirror. She was considered for the role of Alice in Tim Burton's Alice in Wonderland, but the role ultimately was given to Mia Wasikowska. I personally don't know this actress at all, so I can't really comment on how I feel about her joining the cast. Unless they have some severe changes from the original, Shelly doesn't last very long so I wouldn't even consider this a lead role. Sarah was more of a lead support so I'm curious to see who they'll cast in that role.
