Watch: Emma Watson and "Harry Potter" castmate reunite in "Regression"
Emma Watson is doing a different kind of spooky alongside former "Harry Potter" castmate David Thewlis (Professor Remus Lupin) and Ethan Hawke in the thriller "Regression" due in theaters this summer.
In the trailer for the '90s-set thriller, in which Hawke plays an investigator Bruce Kenner trying to track down a cult who once had Watson's character Angela in their clutches -- it seems like someone has cast a memory-erasing spell on her.
"The memories are obviously in there behind some door, it's not that difficult to find a key and free them," insists Thewlis, this time playing Professor Kenneth Raines.
"I could hear chanting. They were wearing black robes," Angela recalls under hypnosis.
"Regression" will hit theaters Aug. 28.
