I'm actually somewhat excited
I consider Cage and Cusack to be actors from the same generation, similar in a way I really can't put the finger on, but I'm happy to see a movie with them two together.
I'm also glad that Cage has the role of the officer, I'm not sure I would be able to take him seriously or if he could handle the role if he was the bad guy. Furthermore, Cusack actually looks very much like the killer with those glasses and I think he would be able to portray the cold demeanor of a serial killer.
