Director Todd Lincoln wanted to clarify with us one aspect that was touched on in MTV's interview with Greene: The CGI. Lincoln wanted to assure us that while there is some CG used, he pushed for a cinematic threat that was created practically.
"The film was done almost entirely practical," Lincoln says. "Spectral Motion physically created a full body apparition based on original concept artwork by Aaron Sims. There is only some subtle CG removal and enhancements."
