Oculus
Deadline gives a bit about her role
"The plot begins a decade after a terrifying family incident left two young children orphans. Although her brother was charged with murder, Kaylie (Gillan) is convinced a haunted antique mirror is the real perpetrator and years later wants to prove that the mirror was responsible for destroying their family. Sackhoff, will play Marie, the mother to a younger version of Kaylie. Director Mike Flanagan co-wrote the script with Jeff Howard".
I like Karen Gillan in Doctor Who and the guy who plays Jamie Lanister, Nikolaj Coster is in it.
So cast seems cool but the actually movie not so much.Have to wait till more comes out about it.
