It seems that is not the case, and in correcting this, the director promised a return to "scary stuff":
Cp is not Hell House at all. Nothing could be further from that. Cp is a spec script Matthew and I wrote right after Pan's Labyrinth. It stayed mostly under the radar but I have been pushing it quietly. Universal has been very supportive and wanted to do it. It's set at the turn of the century and it is a Gothic romance with ghosts.
